Frequently Asked Questions
The block size determines how large each pixel square is. A small block size (e.g. 5px) produces a subtle effect, while a large block size (e.g. 40px) creates a strong mosaic look.
The current tool pixelates the entire image. For selective pixelation of faces or regions, try the Photo Censor tool.
