Frequently Asked Questions

How much does 4× upscaling improve my image? +

4× upscaling quadruples your image dimensions — a 500×500 photo becomes 2000×2000. Combined with AI sharpening, the result looks significantly sharper and clearer.

Will it work on very blurry photos? +

Enhancement works best on slightly soft or low-resolution images. Very heavily blurred photos will show improvement but some detail loss cannot be recovered.

Is it free with no limits? +

Yes, completely free. No account, no daily limits, no watermarks on results.

Are images uploaded to a server? +

No. All processing happens directly in your browser. Nothing is uploaded.
