Blur Part of an Image

Blur only what you choose

Sometimes you only need to hide one thing — a face in the corner, a sign in the background, a number on a screen — while keeping the rest of the photo crisp. This tool lets you drag a box over exactly that area and blur, pixelate, or black it out, leaving everything outside the box at full resolution.

Add as many boxes as you like, each obscured independently, and adjust the strength to taste. When you download, only the selected areas are changed and the effect is flattened into the file — so the rest of your image is untouched and the hidden parts can't be recovered.

How to blur part of an image

1. Open your image. Drag it onto the tool, choose a file, or paste it.
2. Drag over the area. With Selected areas chosen, drag a box over just the part you want to hide. Add more boxes if needed.
3. Adjust and download. Set the blur strength (or switch to pixelate/redact), then download in your original format.

Resize by re-drawing

To change an area, remove it with the small ✕ on the box (or Undo) and drag a new one. Draw the box slightly larger than the detail so nothing identifying peeks out at the edges.
