Remove PDF metadata, including the part most tools skip
Two separate channels store your name: the Info dictionary and the XMP packet. Many cleaners clear the first and leave the second intact.
Why one pass is not enough
The Info dictionary is a small key-value block near the end of the file. Clearing it removes Title, Author, Subject, Keywords, Creator and Producer. But PDF 1.4 and later also carry an XMP packet — an XML block attached to the document catalog — and that block frequently repeats the author, the tool that produced the file, and timestamps. A cleaner that touches only the Info dictionary leaves the packet untouched, and so does the compression pipeline on this site: it clears the Info dict but keeps XMP.
This page reads both, prints both, and removes both. After saving, the output is reopened and the fields are read again, so you can see that the removal actually took rather than trusting a success message.
What it does not touch: the text of the document, embedded images, annotations, or the file's structure. Metadata removal is not redaction — if a name appears in the body text, it stays there.
