Blur Part of an Image
Hide just one area — drag a box over the part to blur and leave everything else sharp, free and in your browser.

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
- Open your image. Drag it onto the tool, choose a file, or paste it.
- Drag over the area. With Selected areas chosen, drag a box over just the part you want to hide. Add more boxes if needed.
- 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.
How blur part of an image works
- What it does
- Selective blur of one or more regions
- How the tool does it
- You drag a box over only the area you want to hide and choose blur, pixelate, or a solid bar; the effect is applied per region and clamped to that box, so every pixel outside your selection keeps its full original resolution.
- What it's for
- Selective obscuring is for when you need to hide just one thing — a face in the corner, a sign in the background, a number on a monitor — without softening or degrading the rest of the photo.
- Can it be reversed?
- Only the boxed areas are altered and the result is flattened into the downloaded file, so the hidden parts can't be recovered while the untouched areas remain pixel-for-pixel identical to the original.
Tip: Draw the box slightly larger than the detail so nothing identifying peeks out at the edges; to resize a box, remove it with its ✕ and drag a fresh one.

Frequently asked questions
How do I blur only one part of an image?
Choose Selected areas and drag a single box over the part you want to hide. Everything outside the box stays sharp.
Can I blur several separate parts?
Yes. Drag a box over each part; every box is blurred independently, and you can remove any one of them.
Does the rest of the image stay sharp?
Yes. Only the areas you box are blurred; the rest keeps its full resolution. The effect is baked in when you download.
Where is my image processed?
The blurring happens in your browser, so the new file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
