Pixelate Image
Pixelate any image online to hide faces, blur sensitive text, or create retro mosaic effects. Adjust the block size for subtle blur or heavy censorship — one click, no software.
How to use the pixelate image tool
- Upload the image.
- Set the pixel block size (5–30 is typical; larger = more obscuring).
- Click “Process Image”.
- Download the pixelated file.
Frequently Asked Questions
What block size should I use?
5–10 for gentle blur, 15–25 for strong pixelation of faces or text, 30+ for heavy obfuscation.
Can I pixelate only part of an image?
The current version pixelates the entire image. For a specific area, first crop the region, pixelate it, then combine — or use the crop tool to isolate the region you want.
Is pixelation secure for hiding faces?
Modern reverse-image and AI tools can sometimes de-pixelate low block sizes. Use 20+ blocks for strong privacy protection.
Does pixelation reduce file size?
Slightly — pixelation creates larger flat-colour regions that compress better in JPEG/WEBP.
