Frequently asked questions

Is my file uploaded anywhere?

No. The document is read, processed and written back by the page itself, in your browser. There is no account and no storage. You can verify it by loading the page, disconnecting from the network, and doing the whole job offline.

Does it really delete the text, or just cover it?

It deletes it. A page carrying a redaction is turned into an image, the zones are painted onto that image, and the image replaces the page — so that page has no text layer left to recover anything from. Pages you did not touch keep their text.

What happens with a scanned document?

A scan has no text layer, so nothing can be detected automatically and nothing can be searched. You draw the zones by hand over the page, with the mouse or with the keyboard, and those are painted like any other redaction.

How large a file can it handle?

Up to 100 MB and 200 pages. The ceilings exist because everything runs in your browser, whose memory is limited; a larger document has to be split and processed in parts.

Are metadata removed as well?

Yes. Document metadata, annotations, file attachments and page thumbnails are stripped from the produced file, because text removed from a page can otherwise survive in any of them.

What does striking through or underlining do?

They annotate, they do not redact. The text stays in the file and remains readable — that is what those tools are for. Only redaction removes anything, and the interface keeps the two apart on purpose.

Can it refuse to give me a file?

Yes, and that is deliberate. The produced file is re-read and searched for every string that was supposed to be gone. If any of it is still extractable, the export is cancelled and nothing is handed over, with the surviving value named so you can act on it.

How much does it cost?

Nothing. There is no account, no trial and no paid tier.
