Image Pixelator

The Image Pixelator is a free online tool that turns your whole picture into a blocky mosaic effect. It is perfect for privacy-conscious users, journalists, and designers who need to censor faces, license plates, or sensitive text. You can use it anywhere to protect identities while keeping the rest of the image intact and visually interesting.

How the Image Pixelator works

  1. 1

    Upload your image into the editing workspace and set the Pixel size from 2 to 60px. Larger cells create a coarser mosaic across the entire picture.

  2. 2

    The engine shrinks the whole image down and scales it back up with smoothing disabled, grouping every group of pixels into one solid color block for the classic mosaic effect.

  3. 3

    The fully pixelated image appears in the preview ready to download. Because the effect covers the whole picture, pair it with cropping if you only need part of the frame obscured.
