How to use this page
- Choose an image.
- Set the block size. Larger blocks hide more detail.
- Pixelate the whole frame, preview, and download at the original dimensions.
Worked example: a mosaic background from a busy street photo
Use a large block size so the scene becomes colour tiles, then place type on top in your layout tool. Do not publish this as a redacted evidence photo.
What this job is for
This is not a selection brush. Crop first if only part of the frame should be in play. Small blocks can leave shapes easy to guess.
Useful limits
If you wanted a smooth wash, use blur instead.
The live tool behind this page is Pixelate Image. It is the same local engine as the rest of Image Cosmos.
