Blur an Image Free, Right in Your Browser

Blur a whole photo, or drag a box over a face, a name or a number plate. The blur is written into the pixels, so what it covers is gone. Free, nothing uploaded.

Quick answer

BatchSet blurs images free and entirely in the browser, with no upload and no sign-up. It blurs either the whole image or one rectangle the user drags over a face, a name or a number plate, and the blurred pixels are written into the saved file, so the detail underneath is gone rather than covered. Strength is a share of the image's shorter side, so it looks the same on a large photo and on a thumbnail. It does not separate a subject from its background. Many images can be blurred at once with a ZIP download.

Frequently asked questions

Can the blur be undone?+

No, and that is the point. The blurred pixels are written into the saved file, so the detail underneath is gone rather than covered by a layer someone could peel off.

How do I blur a face or a number plate?+

Choose Just an area and drag a box over it. Use a high strength: a light blur over small text or a plate can still be readable.

Can it blur the background and keep the person sharp?+

No. This tool blurs a rectangle, or the whole image; it does not work out where the subject is. For a background, blur a rectangle that misses the subject, or use the background remover and rebuild the shot.

What does the strength number mean?+

It is a share of the image's shorter side, not a fixed number of pixels, so the same setting looks the same on a 4000px photo and a 400px thumbnail.

Is it free, and are my images uploaded?+

It is free with no account and no watermark, and nothing is uploaded: the blur runs on your own device.

Can I blur many images at once?+

Yes. With Whole image, every file you add is blurred. With Just an area, the box you drew is used at the same place in each image.
