Frequently asked questions

How do I blur the background of a photo?
Upload your photo and adjust the blur amount. The main subject is detected automatically and stays sharp while everything behind it is blurred.
Does it only work on people?
No. It finds the main subject of any photo, including pets, products, and food.
Will the subject's colors bleed into the blur?
No. The subject is removed before the background is blurred, so its colors do not smear into the background.
What kinds of photos work best?
Photos with one clear main subject, such as a person, pet, or product, give the cleanest results. The subject is found automatically, so no prompt or selection is needed.
What file formats can I export?
You can export as PNG, JPEG, WebP, TIFF, BMP, or HEIC.
Is this tool free to use?
Yes — completely free, no account needed. Your images are processed entirely in your browser and never uploaded to a server. Downloads have no watermarks.
