What it does
- Paint a region into blocks, at a block size you choose
- Or drop a hard black box over it
- Works on faces, plates, addresses, passwords, account numbers
- Exports flattened, so the original pixels are not in the file
Flattened means gone
A redaction that can be undone by whoever receives the file is not a redaction. The export bakes the blocks into the pixels and writes a new file — there is no layer underneath carrying the original, and no metadata describing what was covered. The untouched original stays on your machine only.
Blocks or a box
Pixelation keeps the shape of what was there, which reads better in a screenshot of a UI. A solid box says plainly that something was removed, which is usually what you want for a document. For anything sensitive, prefer the box: large enough blocks are safe, but small ones can sometimes be reversed.
No account needed
Every tool that runs on your own machine works logged out, with nothing to sign up for. Signing in adds sync across your devices and share links; Pro adds the passes that need a server. The no-upload page draws the line between the two, and Architecture shows it table by table.
