Removing PDF metadata clears the author, the title, the creation and modification dates and the software that produced the file — and the XMP packet that quietly duplicates all of it in XML. The pages themselves are untouched. Drop a PDF above and it is rewritten inside your browser.
Every PDF carries an information dictionary: title, author, subject, keywords, creator, producer, and two timestamps. That is what a reader shows under Document Properties, and it is what most tools clear when they say they remove metadata.
Modern PDFs carry the same information a second time, as an XMP packet — a block of XML embedded in the file. Clearing the dictionary and leaving the packet produces a document whose properties dialog is blank and whose bytes still contain the author's name in readable text. Both are removed here.
The producer and creator fields name the software, usually with a version number: which word processor, which export plug-in, which PDF library, sometimes which operating system. For a document sent outside an organisation that is a small piece of infrastructure disclosure, and for a document meant to look like it came from somewhere else it is the detail that gives it away.
The timestamps are the other half. A PDF created at 02:14 on a Sunday says something about how it was produced, and a modification date days after the creation date says the document was revised after it was apparently finished.
The content. Text stays text, images stay images, links stay links, and the document opens exactly as it did — this rewrites the file around the pages rather than rebuilding them.
That also means anything embedded *in* the content survives: a scanned signature is still a picture of a signature, a photograph placed on a page still carries whatever its own metadata said, and text hidden under a black rectangle is still text. Removing document properties is not redaction, and no tool that claims otherwise should be believed.
