How The Tool Works

The tool draws your image to a browser canvas and applies a small sharpening kernel that increases local edge contrast.

The download format is chosen from browser-friendly canvas export types so the saved file extension matches the actual encoded image.

This keeps the workflow private and lightweight for everyday screenshots, photos, and exported graphics.

Best for soft images

Sharpening is most helpful when a source image looks slightly blurred or needs a touch more edge definition.

Moderation helps

A small amount usually looks better than an aggressive pass, which can create halos and noisy edges.

Local preview

You can compare the before and after previews immediately without sending the image anywhere else.
