Sharpen Blurry Photo Online

Blurry photos happen for many reasons: camera shake, subject motion, soft autofocus, or deliberate blur that needs to be undone. Image sharpening applies a convolution filter that enhances edge contrast, making fine details pop and reducing the appearance of softness.

This tool uses an unsharp mask algorithm — the same technique used in professional photo editing software. It enhances the difference between adjacent pixels, making edges appear crisper without introducing visible haloing at low-to-medium intensity settings.

Adjust the sharpening intensity from 1 (gentle correction) to 10 (aggressive sharpening). Start at 3–5 and increase until the result looks right for your image. Over-sharpening at high intensity can introduce noise, so use the minimum effective setting.
