How do I blur the faces in a video?
Open Blurfold and choose a video. Every frame is checked, each face is found and followed through the clip, and the covers appear in the preview straight away. Adjust anything you want, then tap Export to Photos.
Can I leave one person unblurred?
Yes. Tap that person’s face in the video and they stop being covered; tap again to put the cover back. The choice follows them through the whole clip, because it is attached to the person Blurfold is already tracking rather than to a box you drew.
What does the coloured bar under the video mean?
It is a map of how each moment is covered. Green means a face was actually detected there. Amber means the detector briefly lost the face and the cover was bridged across the gap — usually correct, but worth a glance. Grey means there was nothing to cover. Tap anywhere on the bar to jump to that moment.
What is the screen that appears before exporting?
It lists the moments Blurfold is least sure about: any stretch where nothing is being covered, and any guess long enough to be worth your eyes. Each one shows a thumbnail of the real output, a button to jump to it, and a one-tap fix. It exists because we would rather show you the few percent we cannot promise than quietly round up to 100%.
Can it blur licence plates?
Yes — turn on Cover text. Blurfold finds a plate by the readable text on it, so the same setting also covers name badges, addresses, documents and phone screens. It is off by default because covering every sign in a street scene makes a video hard to watch, but if readable text is found and left uncovered the review screen tells you before you export.
Something was missed. Can I cover it myself?
Add your own cover and drag it into place. By default it stays on for the whole clip; if you only need it briefly, scrub to where it should start and tap Starts here, then to where it should end and tap Ends here.
How do I blur an object that moves in a video?
Draw one box over the object on any frame and tap Follow this object. Blurfold finds it on every frame and covers it through the whole clip as it moves. If it misses a moment, show it the object once more on that frame and it looks again. To cover every pet, car, screen, bottle or bag at once, switch on that group under Cover things by type. Covering objects is part of Blurfold Pro.
Is Blurfold free? What is Blurfold Pro?
Covering faces, licence plates and readable text is free, with no limit. Blurfold Pro is a one-time purchase that adds the object tools, and your first three exports with an object covered are free, so you see the result before you pay. No subscription, no ads, no account. After a reinstall, tap Restore Purchase in Support.
Where do my exported videos go?
Into your photo library, in an album called Blurfold. My Videos on the start screen lists them, ready to play or share. Deleting one there deletes it from Photos too.
Will my video come back larger or lower quality?
Neither. Blurfold keeps your video’s own quality settings instead of a fixed preset, so the file comes back about the size it went in rather than several times larger. Length, resolution, frame rate and sound are all kept, and the sound is copied as it is.
Where does my video go?
Your video stays on your iPhone — no account, and no upload unless you choose Share link for a finished video. Then only the blurred copy goes to our servers, for 30 days, and you can delete it any time. Anonymous usage counts (never the video) go to an analytics service, and feedback you choose to send is delivered separately. See our Privacy Policy for details.
How do I send feedback?
Open Send Feedback in Blurfold. Email address and message are required; you can attach up to five optional images. App version, iOS version, device model and language are always included. Location and other photo details are removed from images on your iPhone first.
It struggles when people walk in front of each other.
That is the honest weak spot. Crowd scenes, where people repeatedly cross, are where face tracking is hardest and where Blurfold is least reliable. The coverage bar and the pre-export review show you exactly where — please check them before publishing anything that matters.
