Pixelation vs blur: don't guard privacy with something reversible
Everyday "blur censoring" can be partially reversed with enough reconstruction effort — blurred ID and phone numbers carry real read-out risk. Pixelation turns regions into true large blocks with the original information gone — nobody recovers that. Sensitive info? Always pixelate.
How to censor
Once the image loads, drag a frame over the area — the mosaic paints live, what you see is what you get; nothing selected censors everything, the frame moves whole, corners/edges resize, strength drags live. For several patches, export, re-import and frame the next.
