- Blur strength
- Light, medium, strong
The subject is cut out on your device and your original photo is blurred behind it, so nothing is uploaded and switching strength costs nothing. Each level scales to your photo's size, so medium looks the same on any photo. A wispy edge like loose hair is where any cutout is hardest, so try High Quality mode if the outline looks rough.
A Blur Background Tool Built for a Natural Look
AI accuracy that runs in your browser, with no subscription. Blur the background of any photo in seconds.
AI-Powered Edge Detection
The segmentation model traces hair, fur, and fine edges before it blurs the rest, so the soft background does not bleed into your subject or leave a rough outline.
Adjustable Blur Strength
Choose Light, Medium, or Strong blur. Each level scales to your photo's size, so a medium blur looks the same on a phone shot and a full-resolution photo. Switching strength is instant and never re-runs the AI.
Fast and High Quality Modes
Pick Fast for a quick result on simple shots, or High Quality for wispy hair, pets, or busy backgrounds where the edge needs more care.
Private by Default
The free mode runs the AI model on your own device using WebGL and WebAssembly, so your photo never leaves your browser.
No Signup, No Watermark
The browser mode is free forever. No account, no credit card, and no watermark on your blurred photo. Unlimited uses, unlimited downloads.
Works Offline After First Use
Once the AI model downloads, the tool works fully offline. Blur a photo background on a plane, a train, or with spotty Wi-Fi.

Frequently Asked Questions
Answers to common questions about blurring a photo background online.
How do I blur the background of a picture for free?
Upload your photo and the tool cuts out the subject, then blurs everything behind it automatically. Pick a blur strength and download the result. It runs in your browser at no cost, with no signup and no limit on how many photos you process.
Does blurring the background upload my photo to a server?
No. The default mode runs entirely in your browser using WebAssembly and WebGL, so your photo never leaves your device.
Why does my blurred background have a halo around the hair or edges?
A halo means the cutout missed some fine detail before the blur was applied. Switch to High Quality mode, which uses a larger model built for wispy hair, fur, and busy backgrounds, then reprocess the photo for a cleaner edge.
Can I add portrait mode blur to a photo I already took?
Yes. This tool works on any photo, even one shot without portrait mode or depth data. The AI detects the subject after the fact and blurs the background around it, so it works on old photos, screenshots, and shots from any phone or camera.
What's the difference between blurring a background and removing it?
Removing a background cuts the subject out completely, leaving transparency or a flat colour behind it. Blurring keeps your original photo in place and only softens it, so the setting stays visible but no longer distracts from the subject.
