Frequently Asked Questions

Can I pixelate specific areas only?

Some versions support selective pixelation. Check if area selection is available in your version.

What pixel size should I use?

For privacy censoring, use larger blocks (20-50px). For retro aesthetics, use smaller blocks (5-15px).

Is pixelation reversible?

No, pixelation permanently reduces image detail. The original image cannot be recovered from a pixelated version.

Does it maintain aspect ratio?

Yes, the overall image dimensions and aspect ratio are preserved during pixelation.

Can I create pixel art from photos?

Yes, using very small pixel sizes can create pixel art effects, though results work best with high-contrast images.
