FAQ
Frequently asked questions
What metadata can I edit?
The four standard PDF Info fields: Title, Author, Subject, and Keywords. These are the fields shown in PDF viewer document properties.
How do I clear a field?
Leave the field empty. An empty field clears the corresponding metadata entry in the PDF.
Does this change my PDF content?
No. Only the document metadata (Info dictionary) is modified. All pages, text, images, and annotations are preserved exactly.
Is the metadata visible to others?
Yes. Metadata is embedded in the PDF file. Anyone who opens the file or checks its properties can see it. Use this tool to add or correct attribution.
