Blur Image Online Free
Add a smooth, adjustable blur to your image. Slide from a gentle soft-focus to a heavy frosted effect — handy for creating a soft background, a privacy screen, or hiding sensitive details before you share a screenshot. You can blur the whole image, or drag a box to blur just one area, like a single face.

Blur One Area or All
Drag a rectangle over a face, name or number to blur only that spot — or leave it unselected to soften the entire photo.
