See and remove hidden PDF metadata without uploading your file
Every PDF carries invisible details beyond what's printed on the page — a title field, the name of whoever's user account created it, the software used, and sometimes keywords or a subject line set automatically by an office suite. None of this shows up when you open the file normally, but it's trivially easy for anyone to inspect. DocZap's Remove PDF Metadata tool shows you exactly what's hidden in your document and strips it all in one click.
See before you scrub
Rather than blindly stripping fields you can't see, DocZap reads your PDF's title, author, subject, keywords, creator application, and producer, and displays each one clearly. If a field is empty, it says so. This transparency means you know exactly what information was attached to your file before you remove it — useful if you're curious whether a document you received or created reveals more than you expected.
Why scrubbing metadata locally matters
Metadata often reveals more than people intend — an author field with a full name and job title, a “creator” field naming internal software, or a title field describing an unreleased project. Uploading a document to a third-party metadata scrubber to fix this is a bit self-defeating, since you'd be handing that same sensitive information to another server. DocZap reads and clears every field using pdf-libdirectly inside your browser, so the information you're trying to remove never leaves your device in the first place.
When to scrub metadata before sharing
This matters most before publishing a document publicly, submitting a report to a client or regulator, or sharing a file outside your organization — situations where an author name, an internal project title, or a hint about your software stack shouldn't travel along with the content. Journalists, researchers, and legal teams in particular often scrub metadata before releasing documents to avoid revealing more than intended.
What metadata removal doesn't cover
It's worth understanding the limits of what this tool touches. DocZap clears the document-level metadata fields defined by the PDF specification — title, author, subject, keywords, creator, and producer. It doesn't rewrite the visible content of your pages, so any identifying information printed directly on a page, like a letterhead or a footer with a name, will still be there after clearing metadata; use DocZap's Redact PDF tool for that instead. Similarly, this tool doesn't affect standards-compliant digital signatures, since those are a separate mechanism from the descriptive metadata fields being cleared here.
It only takes a few seconds to check a PDF for hidden metadata, so it's worth making a habit of running any document you didn't create yourself through this tool before passing it along further — a shared template, a form someone else filled out, or an old file pulled from an archive may carry metadata from its original author that has nothing to do with you.
