Blur Background - Blur photo backgrounds privately in your browser

by
Blur Background automatically finds the main subject and adds a natural background blur. Processing runs locally in the browser, so portraits and product photos are not uploaded to a server. It supports adjustable blur strength and instant downloads without an account.

I built Blur Background for people who need a cleaner portrait or product photo without uploading personal images to an unknown server. The local browser workflow keeps the original photo private while making background blur quick and accessible. I would love feedback on edge detection and the range of blur controls.

love that this runs locally, that was the main reason i tried it. one thing that would make it way more useful is letting me batch process a whole folder of photos at once instead of doing them one by one

Honestly the local processing thing sold me right away, and the subject detection actually nailed the edges on a tricky product shot I threw at it. Slider feels smooth too.

Being able to selectively keep another object in focus besides the main subject would be huge for product shots where I want both the item and a brand tag sharp while blurring everything else behind them.
