About Pixelate Image

Pixelate Image turns a picture into a mosaic of square blocks. Each block takes the average color of the pixels it covers, weighted by their transparency. The block size is set either in pixels, from 2 to 50, or as a share of the shorter side, from 1 to 20 percent, which keeps the same look on a small screenshot and on a large phone photo. The whole picture is pixelated: there is no area selection. The mosaic is computed in your browser.

How to pixelate an image

  1. 1Click the upload box and choose the picture to pixelate.
  2. 2Choose "In pixels" and set "Pixel size", or choose "% of the picture" and set the block size.
  3. 3Click "Pixelate".
  4. 4Check the mosaic and click "Download"; JPG, PNG, and WebP originals keep their format, all others come back as PNG.

Where your image is processed

Blocks are averaged by this page in your browser and the picture is not uploaded. The pixelated copy is kept only in the tab until you download it. If an error message appears on screen, its cleaned text, the tool's name, and the browser's name and version are reported to us, never the picture.

Frequently asked questions

Can I pixelate only a face or a license plate?

No. The whole picture is pixelated; there is no brush or rectangle. For one area, use a photo editor with a selection tool, or crop that area with Crop Image if the rest is not needed.

Does the percent mode adapt to the picture size?

Yes. Percent follows the shorter side, so the mosaic looks alike on a small screenshot and on a large phone photo, where even the 50 px maximum of the pixel mode would look fine-grained. Pixels give the same block size on every picture.

Can a pixelated image be reversed?

No. Each block is replaced by one average color, so the detail inside it is gone from the saved file. Your original file is never changed, so keep it if you may need it.
