Metadata FAQs

Frequently Asked Questions

1 What is PDF metadata?
PDF metadata is descriptive information embedded in the file structure. It includes fields like Title, Author name, Subject, Keywords, Creator software, and creation/modification dates.
2 Why should I edit or clear my PDF metadata?
When you share a PDF, others can check your document properties to see who created it, when it was modified, and what app compiled it. Wiping or editing these tags helps protect your personal privacy and corporate identity.
3 Does editing metadata alter my document's text or layout?
No, not at all. The editing process is non-destructive and only modifies the file's information dictionary block. Your document text, pages, layout, and images remain completely unchanged.
4 Can I edit metadata on password-protected documents?
Yes. If the PDF requires a password to open, the tool will prompt you for the password to unlock the document structure locally in your browser memory before updating metadata dictionary values.
5 Are my document contents uploaded to secondary cloud servers?
No. All parsed inputs and dictionary modification scripts execute directly on your browser canvas. The document never leaves your machine, keeping your files completely secure.
