What is image pixelation used for?

Pixelation is primarily used for censoring sensitive information (faces, addresses, phone numbers) and creating retro aesthetic 8-bit video game art.

Can someone undo or un-pixelate my photo?

No. Pixelation permanently averages colors within each block, removing the underlying high-frequency pixel data so it cannot be mathematically reversed.

Are my photos uploaded to a cloud server?

No. Everything is rendered client-side in your web browser using the HTML5 Canvas API. Your pictures never touch any server.

What image formats can I pixelate?

You can upload PNG, JPG, JPEG, WebP, BMP, and SVG files.

What block size should I use to censor private info?

For standard text and ID cards, a pixel block size between 16px and 32px is recommended to ensure text and numbers are completely unreadable.
