How The Tool Works

Sharpening increases contrast along edges, making boundaries between light and dark areas more pronounced.

The adjusted image is saved in an image format supported by your browser. Its file size may differ from the original.

Your image is processed locally in your browser without uploading it to a server.

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.

Check fine detail

Compare small lettering, hair, or textured areas in both previews. Lower the amount if edges look harsh or grain becomes more noticeable.
