About Image Sharpener

Unsharp masking blurs a copy of the picture and pushes every pixel away from that blurred version, which makes existing edges crisper. The threshold leaves smooth areas (skin, sky, noise) alone. It cannot recover detail a shaky or out-of-focus shot never captured.

How to use it

  1. 1Drop your JPG, PNG, WebP and GIF files into the box, paste them, or tap browse.
  2. 2Adjust the settings if the defaults are not what you need.
  3. 3Run the tool. The work happens on your own device.
  4. 4Download each result, or all of them as one ZIP.
