Image Upscaler

Increase a photo's resolution to 2x using an on-device AI super-resolution model, processed in your browser.

Drag a photo here, or choose a file

JPG or PNG, up to 1600x1600.

You can also paste a file directly (Ctrl+V or ⌘V).

This tool runs entirely in your browser. Your file is not uploaded to a server at any point.

AI Upscaling vs Normal Resizing

A standard image resizer enlarges the pixels already present. AI super-resolution analyzes image patterns and predicts additional detail while increasing resolution - it can't recover a perfect original that never existed, but it can produce a more useful enlarged result than simple pixel stretching in many cases.

Frequently asked questions

It runs a real AI super-resolution model directly in your browser (not a simple resize) that predicts realistic detail rather than just stretching pixels - the same general idea as server-based AI upscalers, just running on your own device instead of a server.

No - resizing with no model just stretches existing pixels and looks blurry. This model was trained specifically to add plausible detail when doubling resolution.

The model processes an image in small tiles, so it can handle a large photo without crashing, but processing time still grows with the photo's total size. The limit keeps a run from taking an unreasonably long time.

No - the AI model runs entirely in your browser. The first use downloads the model (a few megabytes), then everything happens on your device.
