About Blur Background
Use AI subject detection to separate a photo into foreground and background, then soften the background. This simulates a portrait-style effect, with results depending on the subject edges.
How to use Blur Background
- Choose a photo with a clearly defined foreground subject.
- Run processing and adjust the blur intensity.
- Inspect the subject edges and download the processed PNG.

Frequently asked questions
Does this blur the whole photo?
The tool attempts to keep the detected subject sharp while blurring the background. If detection misses an area, that part may also be blurred.
Does the AI need an internet connection?
An initial model download needs a connection. Later availability depends on cached assets, your browser, and device resources; offline use is not guaranteed.
Are my image files uploaded?
No. Image processing happens locally in your browser. The website downloads its code and, for AI tools, model assets. Anonymous site usage analytics are separate from your image files.
Is this tool free to use?
Yes. No account or payment is required. Processing capacity depends on your browser, image dimensions, and available device memory.
