PDF metadata
See what a document reveals about its origin, then clear or change it.
- Runs on your device — the file is never sent anywhere
- No sign-up, no watermarks, no daily quotas
- Free, with no limit on how often you use it
How it works
Every PDF carries properties most people never look at: who authored it, what software made it, when it was created and last changed. A document sent to a client, a regulator or a counterparty carries all of that with it, and it is frequently more revealing than the sender realises.
What is in there
Title, author, subject and keywords are set by whoever made the file — the author field is usually a real name or a computer login. Creator and producer name the software, which tells a reader what you use. The creation and modification dates show exactly when the work happened, which can be awkward on anything meant to look prepared in advance.
Removing it
Clearing wipes those fields. This is the standard step before sending a document outside your organisation, and it takes a moment.
What removing metadata does not do
It changes the document's properties only. It does not touch the text or images on the pages, it does not remove anything hidden behind a black rectangle someone drew, and it will not help with content that should have been redacted. Those are separate problems, and the redaction tool on this site handles the second one properly.
Setting it deliberately
Metadata is not only a liability. A proper title and author make a document searchable and sensible in a library or a document management system, so setting them intentionally is often better than clearing them.
PDF metadata — questions
What does a PDF reveal about me?
Usually the author name from your computer account, the software you used, and when the file was created and last modified.
Does removing metadata make my document anonymous?
No. It clears the document properties only. Anything in the page content itself is untouched.
Can I set the fields rather than clear them?
Yes. Choose to set the fields and fill in what you want.
Is my document uploaded?
No. It is read and rewritten in your browser.
