Can I use this to censor information?

Yes. Crank the block size up and text or faces become unreadable. It all runs on your device, so nothing gets uploaded.

What does block size mean?

It's how many original pixels collapse into one solid square. Bigger blocks, coarser look.

Pixelate Image

Average the image into square blocks to censor a face or a license plate. You set the block size.

What this does

Pixelate an image by averaging it into square blocks — useful for censoring a face or a license plate. A slider sets the block size: bigger blocks collapse more original pixels into each solid square for a coarser, more unreadable mosaic. It all runs on your device, so nothing gets uploaded.
