What is PDF Metadata?

PDF metadata is hidden information about the document:

• Title — Document name (not filename)
• Author — Creator or owner
• Subject — Brief description
• Keywords — Search terms (comma-separated)
• Creator — Software that made the PDF
• Producer — PDF generation tool
• Creation Date — When document was created
• Modification Date — When last edited

Why Edit Metadata?

• Proper titles appear in PDF viewers instead of filenames
• Authors get credit in document properties

Privacy cleanup:

• Remove personal information before sharing
• Strip software names that reveal your tools
• Clean dates that show document age

SEO for PDFs:
