AI Upscaling

AI Upscaling is a free tool that uses AI (Real-ESRGAN) to sharpen blurry or small images and enlarge them up to 4x. Restore old photos or low-quality images to high resolution without losing quality.

Drag and drop a PNG, JPG, or WebP image, or click to select one.

The AI scales the resolution up by 4x. The first run may take a moment while the model gets ready.

3

Compare original and result

Compare the original with the 4x-enlarged result to check the sharpness.

FAQ

Q. How much can it enlarge?

Up to 4x. The AI reconstructs detail, so it's far sharper than a simple resize.

Q. Are my images sent to a server?

Upscaling briefly routes through a server for processing, but once the job is done nothing is stored and it's deleted immediately.

Q. Why is it slow the first time?

On the first run it takes time to get the AI model ready. After that, processing is faster.
