Frequently Asked Questions
How does pixelation work?
Vizua divides your image into blocks of the specified pixel size and fills each block with the average color. Larger pixel sizes produce a more pronounced mosaic effect.
Can I use pixelation to hide faces?
Yes — pixelation at high intensity (20-50) effectively obscures faces, license plates, and other identifying details. However, this tool pixelates the entire image. For selective pixelation, use a photo editor.
What pixel size should I use?
For a subtle retro effect, try 5-10. For censoring details, use 20-40. The maximum is 50.
