Privacy Tool
Blur Faces in Photos
Drop a photo — faces are detected automatically. Adjust blur strength, then paint over anything missed or erase where you don't want blur. Everything runs in your browser.
Frequently asked
Will it work on photos with multiple faces?
Yes. The face detector finds all visible faces in the image automatically and blurs them in one pass. If it misses any (which can happen with profile shots or partially covered faces), use the manual brush tool to paint the blur over them yourself.
Does the blur prevent face recognition?
When blur is applied at a strong enough setting (the default is 18, which is moderate), the result is generally not reversible by current consumer-grade tools. For maximum privacy when posting publicly, increase the blur strength and verify the face is no longer recognizable to you before sharing.
Can I unblur or undo a blur?
You can undo blur during editing — use the eraser tool to remove blur from areas you painted by mistake. Once you download the final image, the blur is permanent. Filesmith doesn't store the original, so make sure to keep a backup if you need the unblurred version.
