Frequently asked questions
Is pixelation safe for hiding sensitive data?
Heavy pixelation (20+) is hard to reverse, but for truly sensitive information cropping it out entirely is safer.
What is the difference with blur?
Blur softens smoothly; pixelation creates hard square blocks — the classic censoring and retro-game look.
