# AI image upscaler — enlarge images in your browser, no upload

> Upscale images 2x with on-device AI in your browser, reconstructing detail rather than just stretching. No upload — the model runs on your device.

Enlarge an image to roughly twice its size while reconstructing detail, using a super-resolution model that runs in your browser. The photo is never uploaded.

Upscaling rescues images that are too small for the job — a thumbnail you need at print size, an old photo, a logo that only exists at low resolution. Because the model runs on-device, even confidential or unpublished images stay with you.

Unlike a simple resize, super-resolution reconstructs plausible detail, so text edges and textures hold up rather than turning to mush. The cleaner the input, the more convincing the result; extreme compression or blur caps what can be recovered.

Pair it with the Background remover to enlarge a clean cutout, or follow with Resize & convert and Compress to hit an exact size and format for delivery.

## How to

1. **Add the image.** Drop the picture you want to enlarge onto the tool or browse for it.
2. **Run the upscaler.** The super-resolution model processes the image on your device; weights cache after the first run.
3. **Compare the result.** Check the enlarged output against the original for sharpness.
4. **Download.** Save the higher-resolution image to your device.

## FAQ

### How is this different from just resizing?

Plain resizing stretches existing pixels and looks soft. The upscaler predicts new detail, so edges and textures stay crisper at the larger size.

### How much larger can it go?

Around 2x each dimension (four times the pixels). Run it again for more, though results depend on the source quality.

### What images work best?

Reasonably clean sources upscale best. Heavily compressed or very blurry inputs limit how much real detail can be recovered.

### Is my image uploaded for upscaling?

No. The model runs locally in your browser; the picture is not sent anywhere.
