What this does
Every PDF carries a set of statements about itself — a title, an author, a subject, keywords, and the name of the software that made it — and they travel with the file whether or not anyone meant them to. This is where you read them, correct them, or empty them out before sending a document to somebody who did not need to know which laptop it was written on.
What it will not do
Every tool here says what it cannot do, in its own words, before you rely on it.
- A field left blank is left as it is. To remove one, give it as empty: clear the box here, or --author "" on the command line.
- The two timestamps can be kept or removed, not set. A document that claims to have been written at a time it was not is worse than one that does not say.
- Metadata is what the file says about itself. A name printed on page one is content: use Redact for that.
- XMP properties are matched by the usual dc:, xmp: and pdf: prefixes. A packet that declares those namespaces under other prefixes keeps its own copy, and the two may then disagree.
Questions people ask
How do I remove a field rather than change it?
Empty the box. A field left untouched keeps what it had; a field given as empty is removed from the file.
Does this remove a name printed on page one?
No. That is content rather than metadata — it is drawn on the page. Use Redact PDF for anything printed on the page itself.
Is my file uploaded anywhere?
No. The work happens in this browser tab, on your own machine. There is no server in this product to send a file to, which is why the promise is checkable rather than something you have to take on trust: open your browser's network panel and watch it do the work without making a request.
Is there a size limit, or a limit on how many files?
None that we impose. The limit is your own machine's memory, because that is where the work happens — a few hundred megabytes is comfortable on a laptop, and less on a phone. There is no daily task counter, no queue and no account.
What does it cost, and what is the catch?
Nothing, and there is no paid tier that unlocks features: the whole product is the free one. That is affordable because running it costs us nothing — your computer does the work — so there is no per-file cost to recover, no advertising and no data to sell.
