Remove document metadata from a PDF
Creates a new copy without the document Info record or catalog-level XMP packet. It runs locally and tells you exactly what that does — and does not — remove.

The two document-level records this removes
PDF metadata is commonly stored in two places. The trailer can point to an Info dictionary containing fields such as author, title, subject, keywords, creator and dates. The document catalog can also point to an XMP metadata stream. This tool removes both references and their referenced objects.
The output is saved with automatic metadata updates disabled, so the library does not add a new producer or modification date while doing the cleanup.
This is not a forensic content scrubber
Metadata-like information may also exist elsewhere: visible page text, annotations and comments, form values, attachments, image metadata, filenames, bookmarks, revision history outside the current PDF object graph, or a signed document's evidence. Those are outside this tool's stated scope and may remain.
Always inspect a sensitive result. Removing document metadata also changes the file and can invalidate an existing digital signature; it does not anonymise what the pages themselves say.
Questions
+ Which fields are removed?
The entire trailer Info dictionary and the catalog's XMP Metadata stream are removed, rather than trying to guess which author or date keys matter.
+ Does it remove comments or form answers?
No. Annotations, comments, form values, attachments and visible content are separate parts of a PDF. This tool does not claim to scrub them.
+ Does it preserve a digital signature?
No PDF rewrite can preserve the validity of a signature over the old bytes. Treat the cleaned copy as unsigned and keep the original if signature evidence matters.
+ Can metadata still exist inside an embedded image?
Yes. Images and attachments are not decoded and scrubbed. Their internal metadata is outside the Info and catalog-XMP scope of this tool.
+ Are my files uploaded anywhere?
No. The PDF is read and rewritten by your own browser. Open devtools, watch the Network tab while you run it, and nothing leaves. The page keeps working with your connection switched off, which is the part worth caring about when the document is a payslip, a contract or a medical letter.
