Quick answer
To blur part of an image, open it here, drag a box over the area and download the result. Use a strong blur for faces and backgrounds. For text such as names, emails or card numbers, a solid box is safer, because a light blur or small pixel blocks can sometimes be reversed. The edited copy is a new image, so the original metadata is not included.

How it works
How to blur part of an image online
- 1
Open your photo or screenshot
Drop it onto the tool, paste it with Ctrl+V or Cmd+V, or choose a file. PNG, JPEG, WebP and GIF all work.
- 2
Choose blur or pixelate
Blur gives a smooth haze and Pixelate a mosaic. Raise the strength for faces, and switch to Solid box for text that has to stay secret.
- 3
Drag over each area
Drag a rectangle over every face, name or background you want hidden. Add as many as you need; Undo removes the last one.
- 4
Save the blurred image
Download a PNG, JPEG or WebP, or copy it to your clipboard. The file is created on your device.

How strong the blur needs to be
Blur and pixelation look secure, and on short text they sometimes are not. Pick the mask for what is underneath, not for how it looks.
| Mask | Safe for text? | Look | Use it for |
|---|---|---|---|
| Solid box | Yes | Hard edge | Passwords, keys, card and account numbers, any text |
| Blur (strong) | Usually | Soft haze | Faces, photos, backgrounds, long passages |
| Pixelate (big blocks) | Usually | Mosaic | Faces, avatars, thumbnails |
| Light blur or small blocks | No | Subtle | Nothing secret: short text can be reconstructed |
Why there is no upload
Your photo stays in this tab
Most online editors upload your screenshot to a server to process it, including the parts you are about to hide.
No upload, ever
The file is read by your browser and drawn into a canvas on your device. This page sends no image data anywhere.
Pixels, not layers
Each mask is painted into the image itself. The download has no hidden original under a shape, unlike PDF or slide annotations.
Metadata dropped
The download is a fresh encode, so EXIF details from the original, such as GPS location and camera model, are not copied over.
