See and change what a PDF says about itself — the title, author, subject, keywords and the program that made it. Your file never leaves this page. Everything happens in your browser, and there is no upload endpoint to send it to — that is checked by a build gate that fails if any network code reaches a tool’s bundle.
How to do it
- Drop your PDF onto the box.
- Edit any field, or clear them all at once.
- Save the details and download.
Questions
What is in a PDF’s metadata?
A title, an author, a subject, keywords, and the name of the program that produced it — and often a version number with it. It is separate from the text of the document, and it travels with the file wherever it goes.
Why would I want to clear it?
Because it is frequently filled in without anyone noticing. A document exported from a template can carry the original author’s name; the producer field often identifies your software and its exact version.
Does this change the text of my document?
No. Only what the file says about itself. Anything written on the pages stays exactly as it is — including a name typed into the document itself, which this cannot see.
