MosaicMachine – Video Blur

Blur faces in videos without uploading them anywhere. 100% on-device.

MosaicMachine blurs faces in your videos automatically — and your videos never leave your iPhone.

• AUTOMATIC FACE BLUR Faces are detected and tracked across frames, so the mosaic follows people as they move. No frame-by-frame editing.

• KEEP YOURSELF, HIDE OTHERS Tap any detected face to toggle its blur on or off. Keep your own face visible while hiding bystanders.

• HIDE ANYTHING BY DRAWING License plates, on-screen personal info — just drag over the area you want to hide. The region follows the motion automatically.

• THREE STYLES Choose mosaic, blur, or black bar, and adjust the strength.

• 100% ON-DEVICE Face detection, effects, and export all run on your iPhone. The videos you want to censor are exactly the ones you don't want uploaded — so nothing ever is.

• FREE, NO WATERMARK Every feature is free, with no watermark and no time limit.

• ADS A small banner ad is shown in the app. A one-time Remove Ads purchase hides ads forever (no subscription).
