About Pixelate Image

The Pixelate Image tool reduces an image to visible blocks at an adjustable size, with live preview, undo, redo, and reset. It is used to censor details or apply a retro pixel effect.

Pixelation is a recognisable way to obscure faces or text. Applying it locally is quick, adjustable, and keeps the image off any server.

How to use

Step by step

  1. Drop the image you want to pixelate into the tool.
  2. Adjust the pixel size; larger blocks obscure more.
  3. Watch the live preview and use undo or redo to compare.
  4. Reset if you want to start again, then download the result.

Best practices
