Typical Use Cases

Enlarge small product photos

Upscale low-res product shots to print or listing quality for stores and catalogs.

Revive old family photos

Bring small, low-resolution scans of old photos up to modern screen sizes.

Upgrade web images

Enlarge tiny icons and graphics from the web for use in designs and presentations.

Upscaling works best on images that are merely small, not heavily compressed or blurry. Run Upscale before editing — enlarging first gives the editor more detail to work with. For tiny avatar photos, 4x often produces surprisingly sharp results.

FAQ

How is AI upscaling different from normal resizing?

Normal resizing interpolates pixels and looks soft. AI super-resolution reconstructs edges and textures, so the enlarged image looks naturally detailed.

Will the file size grow a lot?

A 4x upscale creates a much larger canvas, so the file grows accordingly. Recompress the result afterward if size matters.

Is AI Upscale free?

Completely free. All tools on this site are free to use — no sign-up and no usage limits. Ads shown on the site help cover server and development costs.

Are my files safe?

Yes. AI models run directly in your browser — images are never uploaded to a server, so your privacy stays fully in your hands.

How long does AI processing take?

The first run needs to load the AI model (tens of seconds depending on your connection); after that, each image usually takes seconds.
