About this tool
Pixelate an image to a chosen block size to censor or stylize it, processed entirely on a canvas in your browser and downloadable as a PNG.
Frequently asked questions
How does the pixelation work?
The image is shrunk to a tiny canvas and scaled back up with image smoothing disabled, which produces sharp square blocks.
Can I use this to redact sensitive content?
It coarsens detail with large blocks, but heavy pixelation can sometimes be reversed; for true secrecy, cover the area with a solid shape instead.
