How does AI upscaling differ from normal resizing?

Normal resizing (interpolation) just stretches the existing pixels, making the image look blurry. AI upscaling uses a neural network to reconstruct the missing details, sharp edges, and textures as it adds new pixels.

Is my photo actually safe?

Yes. Most other tools upload your photos to a central server. Filemint downloads the AI model to your browser and processes the image locally. Your pixels never leave your hard drive.

Why is it only 2x upscaling?

We use a specifically optimized ESRGAN model that provides the best balance of quality and speed for browser-based execution. 4x upscaling is possible but would often exceed browser memory limits for many users.

Will it work on my phone?

Yes, but be aware that upscaling is a heavy computational task. Modern smartphones can handle it, but it may take 15-30 seconds depending on the image size and your device speed.

Deep Dive: AI Image Upscaler

Enlarge your photos by 2x without losing quality. High-performance AI enhancement running locally in your browser.

Have you ever found a great photo or an old memory, only to realize it’s tiny and blurry? Usually, when you "zoom in" on a photo, it just looks pixelated and messy. That’s because normal software just stretches the pixels. AI Upscaling is different. It doesn’t just stretch the image; it "imagines" the missing details based on millions of other high-res photos it has seen. It reconstructs sharp edges, smooths out noise, and makes a small photo look like it was taken on a much better camera. Our AI Image Upscaler brings this professional-grade tech directly to your browser. We use a powerful neural network (a special type of AI called ESRGAN) to double the size of your images. What’s really clutch is that it happens entirely on your machine. Most "AI" sites make you upload your photos to their servers, where they might be stored or used for training. On Filemint, the AI "brain" downloads once to your browser, and then your computer does all the work. It’s 100% private, super fast, and you don’t even need an account. Whether you’re trying to fix a low-res logo, a blurry phone photo, or just want to make a wallpaper look better, this tool gives you that "pro" look in seconds.

Technical Architecture

ESRGAN Neural Network

The Enhanced Super-Resolution Generative Adversarial Network architecture is optimized for edge-preservation. It uses residual blocks to focus on high-frequency details that are lost in traditional compression.

Hardware Accelerated Tensors

We use TensorFlow.js with the WebGL backend, allowing the upscaling math to run on your GPU. This provides a 10-20x speedup compared to standard CPU processing.
