Frequently asked questions
What is PDF metadata?
Metadata is the document information stored inside a PDF: title, author, subject, keywords, creator, and producer. It shows up in file managers and search results.
Can I remove all metadata?
You can clear every editable field before downloading. The rebuilt file then carries only the basic information PDFs require.
Does editing metadata change the pages?
No. Only the document information block is touched — the pages themselves are copied as-is.
