Frequently asked questions
Can pixelated text be read again?
Sometimes, if the blocks are too small. Text pixelated coarsely is safe, but a light mosaic over a known font can be reversed by comparing against rendered candidates — this has been demonstrated on redacted documents. For anything sensitive use a high strength, or the solid block.
Why does the block size change between images?
It scales with the area you select rather than being fixed. A 40 pixel block would obliterate a small face and barely mark a large one, so tying it to the region keeps the effect looking consistent whatever you are covering.
Can I pixelate the whole image?
Drag a box across all of it. There is no separate control, because covering everything is rarely what people want — the usual task is hiding one specific thing.
