How it works

Blur Image applies its effect directly to the pixel data of your photo in the browser, and the preview updates live as you move the slider so you can see the exact result before downloading — nothing is applied permanently until you save the file.

Tips for best results

Make small adjustments and check the preview often — extreme settings rarely look natural.
Apply one effect at a time so you can undo just that change if it doesn't look right.
Work from the original photo each time rather than editing an already-edited file, to avoid quality loss.
Good lighting in the original photo means you'll need far less editing afterward.

Frequently asked questions

Can I blur only part of the image?

Currently our tool applies blur to the entire image. For selective blurring of specific areas, use a desktop image editor.

How much blur can I apply?

Use the slider to control blur intensity from subtle to very strong.

Does blur reduce file size?

Blur may slightly reduce file size when combined with compression since blurred areas compress more efficiently.

Can I undo the blur?

Click Upload New to start over with the original unblurred image.

What formats are supported for blur?

JPG, PNG and WebP are all supported.

Can I combine this effect with other edits?

Yes. Use one tool, download the result, then upload that file into another tool on this site to layer edits.

Does editing reduce the original file's resolution?

No, this changes how the pixels look, not how many pixels the image has.

Will this work on photos taken with a phone camera?

Yes, any standard JPG, PNG, or WebP photo from a phone or camera works with this tool.
