Quickly obscure faces, license plates, or private documents before sharing photos online.

Tips & Best Practices

Tip 1

Larger block sizes (50-80) are better for completely hiding identities.

Tip 2

Smaller block sizes (4-12) create a subtle mosaic effect.

How block pixelation works

The tool divides your image into a grid based on the size you specify. It samples the color of the top-left pixel in each grid square, and then fills the entire block with that solid color, reducing the overall visual detail.

Privacy first

When dealing with sensitive information like faces or ID documents, uploading to a third-party server is risky. Our tool leverages client-side processing to ensure your private data never leaves your computer.
