Frequently asked questions
Can it fix a very blurry photo?
No. Sharpening improves slightly soft images, but it can’t recover detail that was never captured.
Why does my photo look grainy after sharpening?
Sharpening also boosts noise. If it looks too harsh, use the original or lower the contrast afterwards.
Is Sharpen Image really free?
Yes. There is no signup, no watermark and no paid plan. The site is supported by ads.
Is my data sent to a server?
No. Your file is processed by code running in your browser. The page only downloads the open-source libraries it needs (for OCR, also the language data), never your file.
