🔲 Image Pixelate
Pixelate a whole image for a retro look, or blur private details like faces and number plates before sharing.
About this Image Pixelate
Image Pixelate shrinks your picture into chunky blocks and scales it back up without smoothing, creating the classic mosaic effect. Use a small pixel size for a retro game look, or a large one to hide sensitive content — faces, house numbers, screens and documents — before posting a screenshot publicly.
How to use it
- Choose an image from your device.
- Drag the pixel size slider — bigger blocks hide more detail.
- Watch the preview update live.
- Download the pixelated PNG.
Example
A screenshot with a visible order number is pixelated at 40 px blocks so the number cannot be read when the image is shared in a support group.
Frequently asked questions
Can pixelation be reversed?
Strong pixelation destroys the original detail, which is the point. Keep blocks large (30 px+) for anything truly private.
Does it pixelate only part of the image?
This tool pixelates the whole image evenly. Crop the sensitive area first with the Image Crop tool if you need a tight result.
