常见问题解答

What metadata does this remove?
Title, author, subject, keywords, producer, creator, and creation/modification dates — all the fields a PDF can carry about who made it and how.
Does this remove metadata hidden inside images in the PDF?
No, this clears the PDF document-level metadata fields only. Images embedded in the PDF keep their own data untouched.
Is the file uploaded anywhere to check the metadata?
No. The PDF is parsed and rewritten entirely in your browser — nothing is sent to a server.
