PDF Metadata Remover

Every PDF quietly carries a set of hidden document properties most people never see: a Title, an Author name, a Subject, Keywords, the Creator application, the Producer engine that generated it, and the exact date and time it was created and last modified. This free online PDF metadata remover reads every one of those fields the moment you upload a file, shows you exactly what's exposed, and lets you strip or replace it before the document goes anywhere else — no software to install, no server involved.

That metadata matters more than it looks. An Author field can leak someone's real name or a company username long after a document was supposedly anonymized. A Producer or Creator field can reveal the exact software, version, or even operating system used to make a file. Creation and modification timestamps can undercut a claim that a document is unedited or contradict a story about when something was written — details that matter in legal discovery, journalism, security research, and anywhere a PDF is shared with people who shouldn't learn more about its origin than its content.

Beyond the six visible fields, PDFs commonly embed a second, separate metadata block in XMP format — an XML-based metadata standard many PDF generators write automatically — plus an internal document ID pair in the file's trailer used to link revisions of the same file together. This tool detects and removes both alongside the standard fields, going further than a typical "clear metadata" tool that only blanks the visible Title and Author fields while leaving the XMP block and file ID fully intact and readable by anyone who inspects the file.

You're not limited to deleting everything, either: switch into edit mode to replace any field with your own value instead of clearing it — useful when you want a document to carry a specific title or organization name rather than nothing at all. Everything happens locally using pdf-lib, directly on the file's internal structure, in your browser — the PDF is never uploaded anywhere, and its actual page content, text and images are left completely untouched throughout.
