Blurize: Blur Face in Video

100% OFFLINE & PRIVATE
Everything runs on your phone. Your photos and videos never leave your device — turn off your internet and Blurize still works. This is our core promise, not a setting. No cloud processing, no hidden uploads, no account required.

AUTOMATIC FACE DETECTION
On-device face detection finds every face in a single tap. Each face appears as a thumbnail — select the ones you want to blur and leave the rest sharp. Ideal when only one person in the frame needs to stay anonymous.

MANY CENSOR STYLES
• Gaussian blur — smooth, natural censoring
• Pixelate — the classic mosaic look
• Black & white — desaturate the face
• Solid colour — cover with any custom colour
• Emoji stickers — fun face overlays that track movement
Oval or rectangular masks, so the cover fits the face.

FACES AND LICENSE PLATES
Turn on plate detection and Blurize finds license plates too, so you can blur a number plate before selling a car, posting a dashcam clip or listing a property. It can miss small, angled or distant plates — check the result and add any it missed by hand, with a manual blur box.

PHOTOS AND VIDEOS
The same fast engine works on both. In video, faces stay covered as they move, frame by frame — no jumping, no gaps. You can also add manual blur boxes by hand and keyframe-track them along the timeline, for anything the detector should not decide for you.

FAST NATIVE EXPORT
Powered by your phone's own hardware — no slow uploads, no waiting in a queue. Export straight to your gallery in full quality.

WYSIWYG PREVIEW
What you see is exactly what you get. The preview uses the real export engine, so there are no surprises in the final file.

No microphone access. No face recognition. No AI profiling. No collection of your media — ever. Blurize detects where a face is so it can cover it; it never identifies who it is, and nothing is stored or sent anywhere.

Blurize is built around one simple idea: your photos and videos are yours, and they should stay that way.
