Grayscale vs pixelate?

Grayscale removes color while keeping luminance. Pixelation downsamples into blocks—color may remain with a mosaic look.

Can I control pixel block size?

Yes. Larger blocks mean heavier obfuscation and less detail—useful for privacy redaction or retro effects.

Processing targets the current still frame or single PNG; alpha is preserved unless the filter fills the background.
