Image Blur

Your images are processed locally in your browser and never uploaded to any server.

Blur an image entirely, with a strength slider from gentle soft-focus to complete abstraction. Common uses: hiding sensitive content in screenshots, creating abstract backgrounds from photos, and softening images that will sit behind text. Everything runs locally in your browser; nothing is uploaded.

How to use the image blur

  1. Add one or more images (drag-and-drop or click to browse).
  2. Drag the strength slider: small values soften, large values obliterate.
  3. Press Apply; each image is blurred in a background worker.
  4. Download the blurred images individually or as a ZIP.

Frequently asked questions

Can I blur only part of an image?

Not here: this tool blurs the entire image, stated plainly. Partial blurring (a face, a license plate) needs region selection; crop the region you need blurred with the crop tool, blur it here, then composite it back in any editor.

Is blurring reversible?

A strong blur destroys the underlying detail; that is the point when hiding sensitive content, and it is why the blur is effective. A weak blur on simple graphics can sometimes be partially undone, so never rely on light blur to protect secrets. Use strong settings, or pixelate instead.

What strength should I use to hide information?

40 and above: at that level individual characters and faces are not recoverable. For everything aesthetic (backgrounds, soft focus), 4–15 usually looks best.

Does blurring change the file size?

Usually it shrinks: blur removes high-frequency detail, which is exactly what image compression spends bytes on. Expect 10–30% smaller files at the same quality setting.
