Why use the image blur tool tool from Super Utility Hub?
Sharing photos often means hiding something: a stranger's face, a license plate, a screen with private data. This tool applies a smooth Gaussian blur of any strength to the whole image.
A slider controls blur strength from subtle softening to completely unreadable details. The result downloads as a lossless PNG.

Frequently asked questions
Can I blur just one part of the image?
This tool blurs the whole image. For a single region, crop the area with the cropper, blur it, then paste it back in an editor.
How much blur hides a face?
8–15px on a typical photo makes facial features unreadable; 25px+ is thorough. Test on the source before sharing.
Is the blur reversible?
Practically no — Gaussian blur discards detail that cannot be reconstructed. That is exactly why it is used for privacy.
