FAQ
Mosaic vs blur — which to choose?
Mosaic (pixelation) is stronger for hiding text/plates; blur looks softer for faces. Both are destructive once exported.
Can I mosaic only a region?
Yes, brush or rectangle-select exactly what to hide.
Is it reversible?
No. Exported images have genuinely lost the original pixels under the mosaic.
