Blur Background
Blur the background of any photo for free — AI finds the person, pet or product and keeps it sharp while the background gets a smooth, camera-like blur. Adjust the blur strength and darken the background to make the subject pop, then download a full-resolution JPG or PNG.
Private by design. Your file travels over an encrypted connection to our conversion server, is processed in memory, and is deleted as soon as the result is sent back. Nothing is stored or logged.
Finding the subject needs our AI model, so your photo is sent over an encrypted connection to our server, processed in memory and deleted immediately — it is never stored or shared. The new background is added in your browser. The result is the same size as your photo (up to 50 megapixels).

How do I blur the background of a photo?
Drop the photo in. The AI separates the subject from the background, then blurs only the background. Use the slider to choose how strong the blur is.
Why is my photo uploaded?
Finding the exact outline of a person or product needs an AI model that's too large to run reliably in a browser, so that one step runs on our server. The photo is sent over an encrypted connection, processed in memory and deleted immediately — never stored or shared. The new background is then added in your browser.
Is the result full resolution?
Yes — the output is the same size as your original photo (up to 50 megapixels).
Is it free?
Yes, with no watermark or sign-up. There's an hourly limit per visitor to keep it fast for everyone.
Can I blur a background without uploading?
Our Blur Image tool blurs faces or chosen areas entirely in your browser; for separating a subject from its background, the AI step is needed.
