Is Sharpen Image free to use?

Yes, completely free. No signup, no watermark, no file limit.

Is Sharpen Image safe? Do my files get uploaded?

No upload required. All sharpening happens in your browser using the Canvas API. Your images never leave your device.

Does Sharpen Image work on mobile, iPhone, and Android?

Yes. It works in any modern browser including Safari on iPhone and Chrome on Android.

Can sharpening fix a blurry or out-of-focus photo?

Sharpening enhances edge contrast to make images appear crisper, but it cannot recover detail that was never captured. Slight motion blur or soft focus improves noticeably; heavily blurred photos cannot be fully fixed.

How strong should I set the sharpening?

Start at a low to medium amount and increase gradually until edges look defined but not harsh. Too much sharpening creates halos around edges and amplifies noise, so subtle is usually best.
