Frequently asked questions

What block size should I use?

Larger block sizes create a stronger mosaic effect. Use 10-20px for subtle pixelation and 30px+ for a strong artistic effect.

Can I pixelate only part of the image?

Our tool applies pixelation to the whole image. For selective pixelation, use a desktop editor.

Is pixelation reversible?

No. Once pixelated and downloaded, the original detail cannot be recovered from that file.

What is the difference between blur and pixelate?

Blur creates a smooth out-of-focus effect. Pixelate creates a blocky mosaic pattern by averaging pixels in each block.

Can I use pixelate for privacy protection?

Yes. Pixelation is commonly used to hide faces, license plates and other sensitive details. Use a large block size for stronger privacy protection.
