What Is the Pixelate Tool?

The Pixelate tool divides your image into uniform color blocks, each filled with the average color of that region, creating a mosaic or pixel-art effect.

Use large blocks to cover private details, or small blocks for a retro 8-bit style.

How to Pixelate an Image

Follow these steps:

  • Drop or upload an image.
  • Adjust the block size to control the pixelation level.
  • Click Pixelate and preview the result.
  • Download the result as a PNG file.

Tips

  • 4–12px suits retro pixel art; 32px and above works for covering private details.
  • For large images, resize first with the image resizer tool.
  • Combine with edge detection for pixel-art outlines.
