AI Image Upscaler

Enlarge and sharpen any image 2× or 4× with a neural super-resolution model — it adds detail instead of just stretching pixels. Free, no watermark, and 100% private.

How to upscale an image

1.Drop an image

A photo, product shot, logo or old picture — it never leaves your device.

2.Pick 2× or 4×

A neural network reconstructs detail as it enlarges — cleaner edges than a plain resize.

3.Download

Save a sharper, higher-resolution PNG — free and with no watermark.

The upscaler runs a super-resolution model on your device's GPU, so your images stay completely private and there are no per-image limits. Best on smaller inputs — very large images are enlarged in tiles.

Frequently asked questions

How does AI upscaling work?
A neural super-resolution model reconstructs realistic detail as it enlarges the image, giving cleaner edges and textures than a plain resize that just stretches pixels.
Is the image upscaler free?
Yes — free and unlimited, with no watermark. The model runs on your device's GPU, so there are no per-image limits or costs.
Are my images uploaded?
No. Upscaling runs locally in your browser using WebGL, so your images never leave your device.
Should I choose 2× or 4×?
Use 2× for a quick, high-quality bump. 4× enlarges further (it runs two passes) and is best for smaller source images; very large inputs are processed in tiles.
What's the best input for upscaling?
Smaller, reasonably sharp images upscale fastest and look best. Extremely blurry or heavily compressed images have less detail for the model to recover.
