Frequently Asked Questions
What block size should I use to fully hide a face?
A larger block size (20px+) makes details genuinely unrecognizable; smaller values create a lighter stylistic effect while still showing rough shapes - always check the preview before treating it as true anonymization.
Is pixelating reversible?
No - averaging pixels into blocks permanently discards the original fine detail in that output image, similar to blurring.
Can I pixelate just part of the image?
This tool applies the effect uniformly across the whole image; for partial pixelation, crop the target region out, pixelate it, then recombine in an image editor.
