Frequently asked questions

How do I blur the area you choose in a photo?
Upload the photo, drag a box over the part you want covered, then set the strength and download. The change is baked into the downloaded image.
Can the blur be reversed by someone else?
Not if the strength is high enough. The pixels are genuinely replaced in the saved file, not hidden behind an overlay — but a very light blur on readable text can sometimes be partially recovered, so use a strong setting for anything sensitive.
Does it work on more than one face?
Yes, several at once, and you can add or remove regions by hand before downloading.
Is my file uploaded to a server?
No. The whole tool runs as JavaScript inside your browser, so your file is processed on your own device and never leaves it. You can even load the page, disconnect, and it still works.
Is it free?
Yes — free and unlimited, with no sign-up, no watermark and no cap on how many files you run through it.
