Pixelate or Censor an Image
Pixelate an entire image, or drag a box over a face, license plate, name, or address to censor just that area. Adjust the block size for a coarse or fine mosaic and watch the preview update live. Because everything runs in your browser, sensitive images are never uploaded, which is exactly what you want when redacting private information.
How to pixelate or censor an image
- Drop an image in, or click to browse.
- Choose whole image, or switch to region and drag a box over what to hide.
- Set the block size and download the censored image.
Examples
Censor a face in a screenshot
A screenshot with region mode, a box dragged over the face
The same image with only the face pixelated into a mosaic
Frequently asked questions
Is my image uploaded anywhere?
No. Pixelation happens entirely in your browser. The image never leaves your device, which matters when you are redacting private information.
Is pixelation reversible?
No. Each block is permanently replaced with its average color, so the original detail in that area is discarded in the downloaded file. For sensitive redaction, use a large block size.
Can I censor just part of the image?
Yes. Switch to region mode and drag a box over the area you want to hide, such as a face or an address. Only that rectangle is pixelated.
What block size should I use for redaction?
Larger blocks hide more. For truly hiding text or a face, use a coarse block size so no readable detail remains, rather than a light mosaic.
What formats can I export?
PNG (lossless), JPEG, and WebP. PNG is a good choice for redaction because it will not introduce compression artifacts around the mosaic.
