How can I edit or delete document metadata?
Document metadata typically refers to background information stored with a document, such as the title, subject, author, keywords, date and time the document was created or modified, and the application it was created with.
To delete document metadata in PDFpen/Pro:
1. Launch your document in PDFpen.
2. Choose Inspector > Document Information.
3. Edit or delete any sensitive information appearing in the fields.
Flattening a PDF will strip the document of its annotation layers including links, form fields, attachments, Table of Contents, and bookmarks. Saving a document in TIFF and back to PDF creates a new document, removes most metadata, and is most similar to sanitizing a document.
