How to Process Files Privately Without Uploading Them
Unlock unparalleled data privacy with Filemint. Discover how our "Offline First" approach processes your sensitive files directly in your browser, ensuring they never leave your device. Experience true security and peace of mind.
Privacy Architecture
This tool uses client-side WebAssembly to ensure your data never touches a server. Secure, fast, and privacy-focused by design.
Core Capabilities
- Live syntax highlighting for JavaScript, TypeScript, Python, Java, C++, C#, Ruby, Go, Rust, PHP, Swift, Kotlin, HTML, CSS, SQL, Bash, JSON, YAML, Markdown, and JSX/TSX
- 8 professional dark themes: Dracula, One Dark, GitHub Dark, Night Owl, Monokai, Nord, Solarized Dark, and Rosé Pine
- 8 background options: 5 gradient presets (Cosmic purple, Ocean cyan, Sunset orange, Bloom pink, Mint green) plus 2 solid darks and transparent
- macOS traffic-lights chrome or Windows minimize/maximize/close chrome — with editable filename in the title bar
- 2× retina-quality PNG export and "Copy to clipboard" for instant paste into slides, tweets, or Figma
- Font size control (10–24px), padding slider (16–64px), and line numbers toggle
- 100% browser-based — zero server, zero uploads, works fully offline
Why It Matters
- Social Ready: Code snippets presented beautifully get more engagement on Twitter, LinkedIn, Reddit, and dev communities.
- Presentation Perfect: Drop code images into Figma, PowerPoint, Notion, or course slides without wrestling with LaTeX or syntax plugins.
- Privacy First: Export images of private, proprietary, or sensitive code with absolute zero cloud upload risk.
- Zero Friction: No sign-up, no watermarks, no credit limits — open the tool and start creating instantly.
Quick Start Guide
Paste or type your code into the editor and select the programming language.
Click a theme swatch to instantly change the color scheme — try Dracula, One Dark, or Night Owl.
Pick a background gradient or solid color from the palette row.
Choose macOS or Windows window chrome and optionally enter a custom filename.
Adjust font size, padding, and toggle line numbers for the perfect composition.
Hit "Export PNG" for a crisp 2× high-resolution download, or "Copy Image" to paste directly.

Technical Architecture
Custom Syntax Tokenizer
The syntax highlighter is a purpose-built stateful lexer that scans code character-by-character using a priority-ordered pattern system. It correctly handles block comments, line comments, multi-line template literals, numeric literals (decimal, hex 0x, binary 0b), identifiers (keywords, function calls, Type names), and operators. Each of the 20+ supported languages has its own keyword set for precise colorization. Token types map to 10 theme color roles.
html2canvas DOM Screenshotting
Image export uses html2canvas to rasterize the live DOM preview element at 2× device pixel ratio. The library reads computed CSS styles — gradient backgrounds, border-radius, box-shadows, font stacks, and text colors — and recreates the visual on an HTMLCanvasElement. The resulting canvas is encoded as PNG via toDataURL for download or converted to a Blob via ClipboardItem for the copy-to-clipboard path.
Theme Color Architecture
Each of the 8 themes defines 10 semantic color roles: background (code area), windowBg (title bar), text (plain identifiers), comment, keyword, string, number, function (call names), type (capitalized identifiers), and operator. This separation ensures every token class has an intentional, visually balanced color in every theme, producing consistently readable and beautiful output regardless of language.
