What is Pixelate Image?
Pixelate Image applies a blocky mosaic effect to a photo or screenshot by shrinking detail into larger square pixels. It is useful for stylized edits, retro effects, and privacy-friendly image treatments that need a stronger look than blur.
How to Use Pixelate Image
- Upload an image into the pixelation tool.
- Adjust the block size to control how strong the effect looks.
- Review the preview as the pixel size changes.
- Download the pixelated PNG when it looks right.

Frequently Asked Questions
How do I make the image more pixelated?
Increase the block size slider. Larger blocks create a stronger mosaic effect.
Does this blur the image or create square blocks?
It creates square pixel blocks rather than a soft blur, so the effect looks more like mosaic or pixel art.
What format does it download?
The tool downloads the result as a PNG.
Is the image uploaded to a server?
No. Pixelation happens entirely in your browser.
