Blur faces license plates and people in any video or photo. PutMask is a free video censor app that finds faces automatically blurs or pixelates them and keeps them covered while they move. It works fully offline with no ads and no data collection.

BLUR FACES IN VIDEO AUTOMATICALLY
Face detection finds faces from any angle even faces as small as 10x10 pixels and in crowds. Choose blur mosaic pixelate black and white or a solid color and PutMask tracks each face through the whole clip so you do not blur frame by frame by hand.

BLUR LICENSE PLATES

HIDE A WHOLE PERSON

CENSOR ANYTHING ELSE BY HAND

• Record lets you hold your finger on something and move with it while the video plays
• Key Frame sets points and moves the filter between them
• Detect searches a single frame when the automatic pass misses a face

MOSAIC PIXELATE OR BLUR
Mosaic effect random colors black and white gaussian blur median blur or a solid color fill. Solid color leaves nothing behind and exports fastest. The others always keep some trace of the original picture which is why they look better. Shapes: rectangle ellipse or a line you draw yourself and can draw on or erase later.
