Uses cryptographically secure randomness. **Features:** - Cryptographically secure randomness (Web Crypto API) - Real-time strength meter and entropy calculation - One-click copy to clipboard - Bulk generation (up to 100 at once) - Custom character sets (Symbols, Numbers, Ambiguous chars) - 100% offline-ready and private **Benefits:** - Ultimate Security: Use the same standards as professional security experts. - Total Privacy: Your new passwords never touch the internet. - Time Saver: No more staring at the screen trying to think of something "random." - Custom Fit: Meet any website’s annoying password requirements instantly. **How to use:** 1. **Pick your vibe**: Use the toggles to decide what goes in. Symbols? Numbers? Uppercase? If a site is being picky about rules, this is where you fix it. 2. **Size matters**: Slide that bar! 12 characters is okay for like, a random forum, but 16 or 24 is where it starts getting invincibile. Don’t be afraid to go big. 3. **Instant updates**: Notice how the password changes every time you move a slider? That’s the generator working in real-time. No need to click "submit" a thousand times. 4. **Copy and roll**: Once you see one you like, hit the copy button. It’s securely added to your clipboard so you can just paste it into your app and be done. 5. **Bulk Mode**: If you’re setting up a bunch of accounts at once, switch to the bulk tab and generate like 50 at a time. It’s super useful for developers. **FAQ:** **Q: Why can’t I just use my cat’s name?** A: I mean, you could, but a hacker’s bot already knows your cat’s name from your Instagram. Using a random string makes it so there’s nothing to "guess." It forces the hacker to try every single combination of letters and symbols, which would take thousands of years. **Q: Is this actually random?** A: Yep! We use `window.crypto`, which isWay better than standard `Math.random()`. It uses "entropy" from your computer’s hardware (like tiny fluctuations in heat or mouse movements) to make sure the result is truly unpredictable. **Q: Do you save my passwords?** A: Absolutely not. That’s the whole point of this site! Everything happens in your browser’s memory. Once you close the tab or refresh, those passwords are deleted forever. We don’t even have a database to save them in if we wanted to. **Q: What’s the "Entropy" score?** A: Entropy is basically a measure of how "messy" or random your password is. The higher the bits, the harder it is to crack. We show you a strength meter so you can see when you’ve reached "God Mode" security. **Q: Can I use this for my bank?** A: For sure. In fact, you should! Just make sure you save the password in a secure password manager after you generate it here, because you definitely aren’t going to remember a 20-character random string! --- ### UUID / GUID Generator **URL:** https://www.filemint.dev/tools/uuid-generator **Category:** Security **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser **Popular:** Yes Create UUIDs/GUIDs with support for v1, v4, v5 versions, bulk generation (up to 1000), validation, and customizable formatting. Perfect for developers, databases, and APIs requiring unique identifiers. **Features:** - Full support for UUID v4 (Random) and v1 (Timestamp) - Bulk generate up to 1000 IDs at once - Instant formatting: hyphens vs no-hyphens - Case switching: UPPERCASE vs lowercase - Integrated UUID validation tool - 100% private and runs in-browser **Benefits:** - Avoid Collisions: Never worry about two items having the same ID again. - Dev Efficiency: Rapidly seed databases or test APIs with standard data. - Standardized: Use the same format as professional developers worldwide. - Always Available: Works offline and locally for ultimate reliability. **How to use:** 1. **Pick your flavor**: Choose between v4 (random), v1 (time-based), or others. If you aren’t sure, just stick with v4—it’s the standard for almost everything. 2. **Set the count**: Need just one? Or a thousand? Enter the number you need. Our generator is fast, so don’t be afraid to go big if you need a lot of data. 3. **Format it**: Some apps want the hyphens (like the standard `8-4-4-4-12` look), some don’t. You can toggle that with one click. You can also switch between uppercase and lowercase. 4. **Copy the loot**: Hit "Copy All" to grab your whole batch, or click the little icon next to a single ID to just grab that one. Super convenient for pasting into your code editor. 5. **Validation Check**: Switch to the validation tab if you want to paste a UUID and check if it actually follows the official rules. It’s a great way to debug weird IDs. **FAQ:** **Q: What’s the difference between v1 and v4?** A: V4 is totally random—it’s like rolling a billion-sided die. V1 uses your computer’s clock and a unique network ID to make sure it’s unique. Most people use v4 unless they specifically need to know *when* the ID was made. **Q: Are these IDs really unique?** A: Yes! The math behind a UUID is insane. There are 340 undecillion possible combinations. That’s a 3 followed by 38 zeros. You could give every grain of sand on Earth its own UUID and still have plenty left over. **Q: Is this safe for production?** A: Totally. Our generator follows the official RFC 4122 spec, which is the industry standard. These are the same kinds of IDs used by companies like Google and Amazon. **Q: Can I generate them offline?** A: Yep! Once the page is loaded, the generator lives in your browser. You can go into a literal bunker with no WiFi and it will still keep cranking out unique IDs for you. **Q: Why use this instead of a random string?** A: Because UUIDs have a specific structure that computers can process very quickly. Plus, they’re recognized by almost every programming language and database in existence. --- ### Text to PDF Converter **URL:** https://www.filemint.dev/tools/text-to-pdf **Category:** PDF **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser Paste text, upload.txt/.md files, customize typography and layout, preview estimated pagination, and export a production-ready PDF in seconds.

Download individual pages or all pages bundled as a ZIP archive. **Features:** - Convert PDF pages to PNG, JPEG or WebP format - Resolution control: 72, 96, 150 or 300 DPI output - Quality slider for JPG and WebP compression - Convert all pages, a custom range, or specific pages - Download single images or all pages as a ZIP archive - Instant in-browser rendering — no server, no uploads - Filmstrip thumbnail grid with per-page download buttons - Works offline after initial page load **Benefits:** - Privacy first: your PDF never leaves your computer. - High fidelity: up to 300 DPI for print-quality images. - Flexible: pick exactly the pages you need. - Fast: no server upload queue, renders instantly on your machine. **How to use:** 1. **Drop your PDF**: Drag and drop your PDF file onto the upload area or click to browse your computer. 2. **Choose format & DPI**: Select PNG for lossless quality, JPEG or WebP if you need smaller file sizes. Set the resolution: 72 DPI for quick screens, 150 DPI for high quality, 300 DPI for print. 3. **Pick pages**: Convert all pages at once, enter a range like 2-8, or list specific pages like 1, 3, 5. 4. **Convert**: Click "Convert to Images" and watch each page render in real time with a progress indicator. 5. **Download**: Click any thumbnail to open the full-size preview, then download that page — or download all pages as a ZIP with one click. **FAQ:** **Q: Is my PDF kept private?** A: Yes, absolutely. The entire conversion happens inside your browser using PDF.js. Your file is never sent to any server. You could disconnect from the internet after the page loads and the tool would still work perfectly. **Q: What resolution should I choose?** A: 72 DPI is good for quick screen previews. 96 DPI works well for standard web images. 150 DPI gives high-quality images for most use cases. 300 DPI is print-ready but produces larger files and takes longer to render. **Q: Which format should I use — PNG, JPEG or WebP?** A: PNG is lossless — ideal for documents with sharp text and hard edges. JPEG produces smaller files with slight compression, good for photo-heavy PDFs. WebP offers the best compression-to-quality ratio and is supported by all modern browsers. **Q: Can I convert a password-protected PDF?** A: No. If the PDF is locked with a password, the engine cannot render the pages. You will need to remove the password first, then convert the unlocked file here. **Q: Is there a page limit?** A: There is no hard page limit. Very large PDFs at 300 DPI may take longer and use more memory. For large documents we recommend converting in smaller batches. --- ### HEIC to JPG Converter - Convert iPhone Photos Free **URL:** https://www.filemint.dev/tools/heic-to-jpg **Category:** Image **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser Drop your iPhone HEIC photos and convert them to universally-compatible JPG, PNG or WebP images.

Watch the progress on each photo card as they develop. 5. **Download**: Download each image individually with one click, or grab all converted photos as a single ZIP archive. **FAQ:** **Q: What is a HEIC file?** A: HEIC (High Efficiency Image Container) is the default photo format on iPhone and iPad since iOS 11. It uses HEVC compression to store images at roughly half the size of JPEG with equal quality. The downside is poor compatibility — Windows, most websites and many apps cannot open HEIC files natively. **Q: Are my photos kept private?** A: Yes, completely. All conversion happens inside your browser using JavaScript. Your photos are never uploaded to any server. Disconnect from the internet after the page loads and the tool will still work perfectly. **Q: Can I convert multiple files at once?** A: Yes. Drop as many files as you like into the upload area, or select multiple files from the file picker. Each file converts in parallel and shows its own progress. **Q: Which output format should I choose?** A: JPG is the most universally compatible — every device, browser and app supports it. PNG is lossless and ideal for screenshots or images with sharp text. WebP offers the best compression with high quality but is primarily suited for web use. **Q: Will the converted images lose quality?** A: At 90–100% quality the output is visually indistinguishable from the original. HEIC data is decoded losslessly and re-encoded at your chosen quality. For social media sharing, 85% is usually more than sufficient. --- ### PDF to Text Extractor **URL:** https://www.filemint.dev/tools/pdf-to-text **Category:** PDF **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser **Popular:** Yes Upload a PDF file and extract all readable text content.

For very large files, use strict parsing and minified output for faster render times. **Q: How are duplicate headers handled?** A: You can choose to suffix duplicates, keep duplicates as-is, or flag them as issues in diagnostics. **Q: Can I produce nested JSON?** A: Yes. Use the nested output mode and dot-style headers like `user.name` or `address.city`. **Q: What happens when row column counts differ?** A: The diagnostics tab reports mismatches, and strict-column mode can enforce a fixed width. --- ### JSON to CSV Converter **URL:** https://www.filemint.dev/tools/json-to-csv **Category:** Data **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser Paste or upload JSON and generate production-ready CSV for Excel, Google Sheets, reporting pipelines, and exports. **Features:** - Configurable nested flattening strategies - CSV controls: delimiter, quotes, line endings, BOM - Boolean and null formatting controls - Column manager with include/exclude and ordering - Interactive table preview with sorting/filtering - Local-only conversion and direct CSV export **Benefits:** - Interoperability: move API data into spreadsheet workflows quickly. - Control: shape output columns and formatting before export. - Reliability: preserve schema alignment across irregular rows. - Privacy: keep sensitive JSON local to your machine. **How to use:** 1. **Load JSON input**: Paste JSON directly or upload a.json file. 2. **Choose flattening + CSV options**: Set delimiter, quote style, nested-key mode, and line-ending behavior. 3. **Adjust columns**: Include/exclude and reorder columns from the generated schema. 4. **Validate with preview**: Use table preview, sort, and filter to confirm output quality. 5. **Export CSV**: Copy or download the generated CSV for spreadsheets or pipelines. **FAQ:** **Q: Does it handle nested objects?** A: Yes. Nested keys can be flattened using dot, underscore, bracket, or stringify mode. **Q: Can array values be exported cleanly?** A: Yes. Arrays can be joined into one cell with a custom separator or emitted as JSON strings. **Q: Is the conversion local?** A: Yes. Processing happens in your browser; data is not uploaded to a backend for conversion. **Q: Can I make CSV more Excel-compatible?** A: Yes. Enable UTF-8 BOM and CRLF line endings for stronger Excel interoperability. **Q: What if my JSON schema is inconsistent?** A: The converter infers a union of keys and leaves missing cells empty so row alignment is preserved. --- ### Image to PDF Converter **URL:** https://www.filemint.dev/tools/image-to-pdf **Category:** Image **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser Upload multiple images, reorder pages, rotate as needed, and export a clean PDF locally in your browser.

Your personal photos stay exactly where they belong—on your device. **Q: Will it make my photo blurry?** A: If you’re making a photo smaller, it will look super sharp. If you try to make a tiny photo 10 times bigger, it might look a bit pixelated—that’s just how math works! But for 99% of what people need, it looks great. **Q: Does it remove my location data?** A: Yep! For your privacy, we strip out a lot of the metadata (like GPS and camera details) when we create the new resized version of your photo. It’s a great extra security feature. **Q: Can I resize multiple photos at once?** A: Right now, our resizer works one photo at a time so you can get the crop perfect. For bulk work, check out our compressor tool! **Q: Why does the preview look big?** A: We show you a preview so you can see what you’re doing, but the download will be exactly the pixel size you typed in the boxes. --- ### JPG to PNG Converter **URL:** https://www.filemint.dev/tools/jpg-to-png **Category:** Image **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser Upload JPG/JPEG files and export PNG versions in-browser.

Your personal photos stay exactly where they belong—on your device. **Q: Will I lose quality?** A: Technically, yes, because JPG is "lossy." But honestly, if you keep the quality slider at 80% or above, you probably won’t even be able to tell the difference without a microscope. It’s a great trade-off for the smaller size. **Q: What happens to transparency?** A: JPG doesn’t support transparency. If you have a logo with a clear background, it will turn into a solid color (usually white). If you *must* have transparency, you have to stay with PNG. **Q: Why is JPG smaller?** A: JPG uses a math trick called "discrete cosine transform" that groups similar pixels together. PNG records every single pixel individually, which is why it’s so much bigger. **Q: Is there a limit?** A: not possible!

Double check the error message for the exact line constant. **Q: Can it handle huge files?** A: Yep! We use a streaming-style parser so you can paste in logs that are multiple megabytes large without crashing your tab. Just give it a second to "color in" the text if the file is massive. **Q: What is "Minify"?** A: It’s the opposite of beautifying. It removes every single space and newline to make the file size as small as possible. Great for production apps where every byte counts! **Q: Is it free?** A: Yep, always. We don’t have server costs because your computer does the work, so we keep it free for everyone without any annoying "Pro" limits. --- ### XML to JSON Converter **URL:** https://www.filemint.dev/tools/xml-to-json **Category:** Data **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser Transform XML data into clean, nested JSON format with customizable options.

Check those tags to make sure they look right. 5. **Copy & Share**: Hit the copy button and you’ve got a perfectly formatted XML doc ready for the legacy system. **FAQ:** **Q: Is my data safe?** A: 100% yes. We don’t even see it. All the conversion happens in your own browser using JavaScript. Your sensitive or private data stays exactly where it belongs—on your computer. **Q: Why does it need a "Root" element?** A: Unlike JSON, a valid XML document *must* have exactly one main tag that contains everything else. You can call it whatever you want, but it has to be there for the file to be "well-formed." **Q: How do you handle JSON arrays?** A: By standard, we repeat the tag for each item in the array. So an array called "items" becomes `......`. It’s the most compatible way to handle lists in XML. **Q: What happens to special characters?** A: We automatically escape things like `&` and `<` into `&` and `<` so your XML doesn’t break and stays valid. **Q: Is it free?** A: Yep, always. We don’t have server costs because your computer does the work, so we keep it free for everyone without any annoying "Pro" limits. --- ### YAML to JSON Converter **URL:** https://www.filemint.dev/tools/yaml-to-json **Category:** Data **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser Transform YAML data into JSON format.

We don’t even see it. All the conversion happens in your own browser using JavaScript. Your sensitive or private config data stays exactly where it belongs—on your computer. **Q: Why is YAML so picky about spaces?** A: Because YAML doesn’t use brackets `{}` or quotes `""` to separate data. It relies entirely on the level of indentation to know what belongs to what. That’s why converting to JSON (which uses brackets) makes it so much more stable. **Q: Does it handle multi-document YAML?** A: Currently, we focus on single-document YAML (the most common kind). If you have the `---` separator, we’ll usually just process the first block or attempt to merge them into a single object. **Q: Can I go back from JSON to YAML?** A: Yes!

Make sure it’s valid JSON first! 2. **Instant "De-clutter"**: Watch all the brackets and quotes disappear as the YAML version builds on the right. 3. **Adjust the Indent**: Choose whether you want 2 or 4 spaces for the indentation. 2 is standard for YAML, but 4 looks great for docs. 4. **Check the Flow**: Verify that the lists and objects are nested correctly without all the bracket noise. 5. **Copy & Document**: Hit the copy button and you’ve got a clean, professional YAML file ready for your project. **FAQ:** **Q: Is my data safe?** A: 100% yes. We don’t even see it. All the conversion happens in your own browser using JavaScript. Your sensitive or private JSON data stays exactly where it belongs—on your computer. **Q: Why is YAML better for docs?** A: Because it avoids "visual noise." In JSON, 50% of the characters are just structural (brackets, quotes). In YAML, basically every character is actual data. It’s much easier for people to scan and understand. **Q: What happens to JSON arrays?** A: In YAML, arrays become bulleted lists (starting with a dash `-`). It looks way more like a normal list than a bunch of square brackets. **Q: Can I go back if I need to?** A: Totally! We have a "YAML to JSON" tool too for when you need to put the data back into a computer-readable format. **Q: Is it free?** A: Yep, always. We don’t have server costs because your computer does the work, so we keep it free for everyone without any annoying "Pro" limits. --- ### Universal Data Converter **URL:** https://www.filemint.dev/tools/data-converter **Category:** Data **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser Powerful all-in-one data converter supporting bidirectional conversion between JSON, YAML, XML, CSV, and plain text.

We use a modern UTF-8 safe wrapper so your emojis and special characters won’t turn into "???" after decoding. **Q: Is Base64 encryption?** A: No! Base64 is just "encoding." Anyone with a decoder (like this one) can read it instantly. Don’t use it for passwords unless you’re also using a real hash or encryption! **Q: Is it free?** A: Yep, always. We don’t have server costs because your computer does the work, so we keep it free for everyone without any annoying "Pro" limits. --- ### Hash Generator & Checksum **URL:** https://www.filemint.dev/tools/hash-generator **Category:** Security **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser Create secure cryptographic hashes for password verification, file integrity checks, and digital signatures. Supports multiple SHA algorithms. **Features:** - Support for MD5, SHA-1, SHA-256, and SHA-512 - Real-time generation as you type - Interactive hash comparison tool included - High-security Web Crypto API implementation - One-click copy for all results - 100% private and runs entirely in your browser **Benefits:** - Security: Generate hashes for passwords without cloud risks. - Verification: Check if a downloaded file is exactly what it claims to be. - Integrity: Ensure your project files haven’t been tampered with. - Education: Learn how modern cryptography works in real-time. **How to use:** 1. **Paste Your Text**: Drop your password, secret key, or document text into the box. 2. **Select Your Algorithm**: Choose SHA-256 for maximum security.

We don’t even see it. All the hashing happens in your own browser using the high-security Web Crypto API. Your sensitive text or passwords never leave your device. **Q: Can I reverse a hash?** A: not possible! Hashing is a "one-way" street. You can turn text into a hash, but you can’t turn a hash back into text. That’s why it’s so great for security—even if someone steals the hash, they still don’t know your password. **Q: Which algorithm should I use?** A: Always use SHA-256 for security. MD5 and SHA-1 are old and have "collisions" (flaws), so they’re only used for basic file checking these days. **Q: Why does the hash change so much?** A: That’s the "avalanche effect." These algorithms are designed so that even a 1-bit change in input causes a massive change in output. It makes it impossible to guess what changed. **Q: Is it free?** A: Yep, always.

We don’t even see it. All the matching happens in your own browser using JavaScript. Your sensitive logs or test strings stay exactly where they belong—on your computer. **Q: What are "Flags"?** A: Flags are modifiers that change how the search works. "g" (Global) means find every match instead of just the first one. "i" means ignore uppercase vs lowercase. **Q: Why does Regex look so weird?** A: It was designed to be extremely compact for old computers. Every character is a shortcut. For example, `d` means "any digit" and `+` means "one or more." **Q: Can I use this for search and replace?** A: Yes! We have a dedicated "Replace" mode where you can test how your text will look after a transformation before you actually run it in your code. **Q: Is it free?** A: Yep, always. We don’t have server costs because your computer does the work, so we keep it free for everyone without any annoying "Pro" limits. --- ### File Checksum Verifier **URL:** https://www.filemint.dev/tools/file-checksum **Category:** Security **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser Calculate and verify file checksums to ensure downloads are authentic and unchanged.

All the hashing happens in your own browser using the high-security Web Crypto API. Your private files never leave your device. **Q: What is MD5 vs SHA-256?** A: MD5 is an older, faster "receipt" that is mostly used for checking for basic mistakes. SHA-256 is the modern standard used for security and anti-tamper verification. **Q: Why does it take longer for big files?** A: Because we have to look at every single byte in the file to generate the fingerprint. If the file is 5GB, that’s a lot of math for your computer to do! **Q: Can I verify multiple files at once?** A: Currently, we handle one file at a time to ensure maximum speed and prevent your browser from slowing down. **Q: Is it free?** A: Yep, always. We don’t have server costs because your computer does the work, so we keep it free for everyone without any annoying "Pro" limits. --- ### ICO Converter & Favicon Maker **URL:** https://www.filemint.dev/tools/ico-converter **Category:** Image **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser **Popular:** Yes Create professional favicons and.ico files from any image.

All decoding is done using JavaScript in your browser. We never send your token to our servers, so your secrets stay secret. **Q: What does "exp" mean?** A: It stands for "expiration." It’s a Unix timestamp telling the website when to stop trusting this token. If it’s in the past, your login session is dead! **Q: Is a JWT the same as a password?** A: No! Think of a password like your house key, and a JWT like a "visitor badge." The badge proves you already proved who you were with the key. **Q: Can I see the signature?** A: We show the raw signature (the blue part), but without the secret key from the server, you can’t see what’s "inside" it—it’s just a mathematical proof. **Q: Is it free?** A: Yep, always. We don’t have server costs because your computer does the work, so we keep it free for everyone without any annoying "Pro" limits. **Q: Which algorithms can this verify locally?** A: The in-browser verifier supports HMAC algorithms HS256, HS384, and HS512. RSA/ECDSA tokens can still be decoded and audited, but signature verification requires appropriate server-side keys. --- ### Unix Timestamp Converter – Epoch to Date & Back **URL:** https://www.filemint.dev/tools/timestamp-converter **Category:** Data **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser **Popular:** Yes Instantly convert Unix epoch timestamps to readable dates or turn any date into a Unix timestamp.

One-click copy to grab the current timestamp for use in your code. **FAQ:** **Q: What is Unix time (epoch)?** A: Unix time is the number of seconds elapsed since 00:00:00 UTC on January 1, 1970, not counting leap seconds. It's the universal time reference in computing—used by databases, APIs, JWTs, file systems, and every programming language. **Q: How do I know if my timestamp is in seconds or milliseconds?** A: A 10-digit number is almost certainly seconds (valid until year 2286). A 13-digit number is milliseconds, which JavaScript's `Date.now()` returns. Our converter auto-detects this based on magnitude. **Q: What is ISO 8601?** A: ISO 8601 is the international standard for representing date and time. It looks like `2025-01-01T00:00:00.000Z`. The `Z` means UTC. It's the safest format for data interchange because it's unambiguous regardless of locale. **Q: Why do timestamps use 1970 as the starting point?** A: The Unix operating system was being developed around 1970, and the engineers needed an arbitrary epoch. January 1, 1970 was chosen as a convenient round date. Timestamps before 1970 are represented as negative numbers. **Q: Is this tool private?** A: Yes, completely. All conversions use your browser's native `Date` object. No data ever leaves your device. Works offline too. **Q: What is "relative time"?** A: Relative time shows how far in the past or future a timestamp is, like "3 hours ago" or "in 12 days." It's calculated by comparing the timestamp to right now, so hitting the same timestamp at different moments shows different relative values. --- ### Code to Image Converter – Beautiful Code Screenshots **URL:** https://www.filemint.dev/tools/code-to-image **Category:** Image **Free:** Yes — no account, no limits **Privacy:** All processing happens in the browser **Popular:** Yes Turn any code snippet into a beautiful, shareable image.

Each has its own keyword set for accurate coloring. **Q: Will the export look exactly like the preview?** A: Yes! The preview is the actual DOM element that gets captured by our screenshot engine. What you see is exactly what you get in the PNG. The export is 2× resolution so it looks crisp even on retina/HiDPI displays. **Q: Is my code kept private?** A: Completely. The syntax highlighter, theming, and image export all run inside your browser. Your code never touches any server. You could go offline after loading the page and the tool would still work perfectly. **Q: Can I use these images commercially?** A: Yes. The generated images are yours. Use them on social media, in blog posts, YouTube thumbnails, presentations, course materials, or anywhere else. No attribution required. **Q: What resolution is the exported PNG?** A: We export at 2× device pixel ratio, meaning a code block that appears 600px wide in the browser exports as a 1200px wide PNG with crisp, sharp text. This looks perfect on retina screens and high-quality prints. **Q: Why does the font look different on some systems?** A: The tool uses system monospace fonts (Consolas on Windows, Menlo on macOS, Liberation Mono on Linux) which guarantees they render correctly in the exported image. This ensures consistent, beautiful output across all operating systems. --- ## Tool Categories ### Data - [CSV to JSON Converter](https://www.filemint.dev/tools/csv-to-json) - [JSON to CSV Converter](https://www.filemint.dev/tools/json-to-csv) -
