よくある質問
どの metadata is removed from PDFs?
Title, Author, Subject, Keywords, Creator, Producer are cleared. Creation and Modification dates are reset. The actual PDF content (text, images, formatting) remains unchanged.
Does this work with scanned PDFs?
Yes. Metadata removal works on all PDFs regardless of content type — scanned images, text documents, or mixed content.
Can I remove metadata from password-protected PDFs?
The tool attempts to process encrypted PDFs, but fully password-protected files that prevent modification cannot be cleaned. You would need to unlock them first.
