FAQ

Can I use this to censor faces or sensitive information?

Yes. Set a large block size (40+) to effectively obscure faces, license plates, or any sensitive content in your images.

What block size should I use for pixel art?

For a retro pixel art look, try block sizes between 8 and 20. Smaller values give a subtle effect while larger values create a more dramatic mosaic appearance.

Is my image uploaded to a server?

No. All processing happens locally in your browser using HTML5 Canvas. Your images never leave your device.
