Blur Image Online

Apply a Gaussian blur to your photo and set its radius in pixels: the setting stays editable until you export.

The editor is designed for a computer or tablet: open this page on a larger screen to edit your image.

How does it work?

Drop your image: it opens in the editor with a 5-pixel Gaussian blur already applied. In the right-hand panel, under “Adjustments and filters”, set the Gaussian blur slider from 0 to 50 pixels: the larger the radius, the blurrier the image.

The adjustment is non-destructive: it stays editable until you export, and 0 restores the original image. To blur only part of it, duplicate the layer, blur the copy and erase an area of it with the eraser. Finally, click Export.

Examples

A subtle background for a headline

A 1920 × 1080 pixel photo used as a background for a title: an 8-pixel blur softens the details while keeping the colors, and the title added on top stays perfectly readable.

A blurred background with a sharp subject

On a 3000 × 4000 pixel portrait, duplicate the layer, apply a 15-pixel blur to the lower copy, then erase the background of the upper layer with the eraser (diameter 200): the subject stays sharp in front of a blurred background.

Frequently asked questions

Is blurring enough to hide sensitive information?
Not always: slightly blurred text or a face can remain recognizable. To hide a license plate, a name or a number, cover the area with an opaque shape (Shapes tool), then check the exported image.
Does the radius depend on the image size?
The radius is measured in document pixels: 10 pixels blur a small image more than a large one. If you scale the image down on export, the blur is scaled down in the same proportion, and the result matches the preview.
Can I undo my changes?
Yes: Ctrl/Cmd + Z undoes, Shift + Ctrl/Cmd + Z redoes, and the “History” tab lets you go back several steps (40 steps per document). A move, a brush stroke or a slider adjustment counts as a single step.
Are my images uploaded to a server?
No. Images are opened, edited and encoded in your browser, on your device. No image, file name or layer text is uploaded: you can even go offline once the page has loaded. Closing the tab erases your work in progress.
