About Pixelate Image
Pixelating works by shrinking the image to a fraction of its size and scaling it back up with smoothing switched off, so each source block becomes one flat square. That is genuinely destructive — unlike a blur, the original pixel values inside each block are averaged away and cannot be recovered.
How to use it
- Choose an image, or drag one onto the drop zone.
- Set pixel size.
- Check the preview, then download. Your original file is never modified.

Questions
What block size is safe for redaction?
Large enough that the region is unreadable at full zoom — for a face, at least 12–16 blocks across the whole face, not per feature. Small blocks on text have been reversed before by matching against rendered candidates.
Which file types can I use?
JPG, PNG, WEBP, GIF, BMP, AVIF and SVG — anything your browser can display. Because decoding is handled by your browser rather than a conversion server, support tracks whatever your browser can already open.
Is there a file size limit?
No imposed limit — there is no server quota to hit. The real ceiling is your device's memory, since the whole file is held in RAM while it is processed. Desktop browsers cope with very large files; phones give up sooner.
What are the limits on pixel size?
It accepts 2 to 80px, starting at 12px.
