Full Image Pixelate
Apply a mosaic pixel effect to the entire image with adjustable pixel size from 2px to 50px.
100% Private
All pixelation runs in your browser. Images never leave your device — nothing is uploaded to any server.
Area Selection
Draw a rectangle to pixelate only a specific area — perfect for censoring faces, text, or sensitive information.
Adjustable Intensity
Control pixel size from 2px (subtle) to 50px (heavy pixelation). See changes instantly in the live preview.
High Resolution
Pixelation is applied at the original image resolution. The output maintains full image dimensions.
Privacy Protection
Censor license plates, faces, addresses, or any sensitive content before sharing images publicly.
How It Works

Choose Mode
Select 'Full Image' to pixelate everything, or 'Select Area' to censor a specific region.

Frequently Asked Questions
The tool scales the image (or selected region) down to a tiny size, then scales it back up with no smoothing. This creates the characteristic blocky pixel effect.
Yes! Switch to 'Select Area' mode and draw a rectangle over the area you want to pixelate. Only that region will be affected.
No. Pixelation permanently destroys detail in the affected area. The original image on your device is not modified — pixelation is only applied to the downloaded output.
For effective censoring (faces, text, etc.), use a pixel size of 15-30px. This ensures the content is unrecognizable while still looking clean.
The tool accepts JPG, PNG, and WebP images. Output is always saved as PNG to preserve quality.
No. All pixelation processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
