Is pixelation better than blurring for censoring text?

Both are effective, but pixelation creates distinct geometric blocks that completely mask letterforms.

Is my original unredacted image safe?

Yes. The entire transformation happens in your browser RAM, so the unredacted version is never uploaded anywhere.

Can I choose between square pixel blocks and circular mosaic dots?

The tool uses clean square pixel blocks for maximum visual coverage and traditional 8-bit retro gaming styling.

Is pixelation permanent in the downloaded file?

Yes. The exported image file contains only the pixelated raster data; the original details cannot be extracted from the file.

What is Pixelate Image?

Pixelate Image applies mosaic pixelation filters to photographs for privacy censoring or retro 8-bit pixel art aesthetics. Adjust the block size slider to control whether you get a subtle mosaic effect or heavy privacy censorship over faces, credentials, or license plates.
