Portrait blur

Blur a Photo Background and Highlight the Subject

A free tool that adds a professional bokeh effect: it keeps your subject sharp and blurs everything behind it, just like an expensive camera lens. Runs in your browser with no uploads.

The tool uses the same segmentation model as background removal: it isolates the subject first, then blurs only the background and composites the sharp subject on top. The result resembles professional portrait photography.

Blur strength is adjustable with a live slider, and the image is recomposited instantly without re-running the model — so you can try several levels quickly until you get the look you want.

How to use it — step by step

1. Drop a photo with a clear person or product.
2. Wait for the AI to isolate the subject.
3. Move the “Blur strength” slider until you like the result.
4. Compare “before” and “after”, then download.

Why processing inside your browser?

Your image never leaves your device. Most competing sites upload your photos to their servers to process them; this tool runs entirely in the browser. No upload, no account, no waiting and no limits — because your own device does the work.

Frequently asked

›How is this different from background removal?

Removal deletes the background entirely; this keeps it but blurred — preserving the photo's context and mood.

›What blur strength should I use?

Between 12 and 20 looks natural. Very high values look artificial.

›Does it work with more than one person?

Yes, the model isolates all people in the frame together.

›Is my photo uploaded?

No. Everything happens inside your browser.
