Sharpen Image — Enhance Edge Clarity
Sharpen soft or slightly out-of-focus photos to boost clarity and detail: adjustable strength, tune in real time. Works on desktop, tablet & mobile — batch, local, no upload.
Sharpening increases the contrast between neighboring pixels so edges and details look crisper. This tool uses a 3×3 convolution for edge sharpening with adjustable strength — good for rescuing slightly soft or mis-focused photos, or making text and textures cleaner. Note this is classic sharpening, not AI deblur — it cannot restore heavily blurred or shaky shots. Processing runs entirely in your browser — no upload.

Sharpen FAQ
It can boost clarity somewhat, but this is classic edge sharpening, not AI deblur — heavy out-of-focus or motion blur cannot be restored.
No. Sharpening is computed locally with the browser Canvas — your image never leaves your device.
Too much strength over-amplifies edge contrast, creating halos and noise. Lower the strength.
Yes — upload a batch, apply one strength to all, then download as a single ZIP.
