FAQ
What is PDF metadata?
PDF metadata is descriptive information embedded in a PDF file that does not appear in the document content. It includes fields like Title, Author, Subject, Keywords, Creator (the application that created the document), and Producer (the application that converted it to PDF). This data is used by search engines, document management systems, and operating system file explorers.
Will editing metadata change the PDF content or layout?
No. Metadata editing only modifies the descriptive information fields. All pages, text, images, fonts, and the visual layout of the document remain completely unchanged.
Is the PDF uploaded to a server?
No. The pdf-lib JavaScript library runs entirely in your browser. Your PDF is read from your local disk, modified in memory, and downloaded back to your device — it never touches any server.
Can I edit password-protected PDFs?
This tool does not support password-protected PDFs. If your PDF requires a password to open, you'll need to remove the password first using another tool before editing the metadata.
How are keywords formatted in PDF metadata?
Keywords in PDF metadata are typically stored as a comma-separated string, for example: 'annual report, finance, 2026'. Enter your keywords in the same format. Different PDF readers and search engines may parse them differently.
