What is PDF Metadata?
PDF metadata consists of document properties that describe your file but don't appear in the visible content. This information helps organize, search, and identify documents.
Types of PDF Metadata
Standard Properties
- Title - The document's official name
- Author - Person or organization who created it
- Subject - Brief description of the content
- Keywords - Searchable tags for categorization
Application Properties
- Creator - Software that originally made the document
- Producer - Application that created the PDF
- Creation Date - When the document was first created
- Modification Date - When it was last changed
Custom Properties
Some PDFs contain custom metadata fields for specialized workflows, including project codes, department names, or version numbers.
Why Metadata Matters
Document Organization
Well-organized metadata makes documents easier to find and manage. Search systems can index these properties for faster retrieval.
Professional Presentation
PDF readers display metadata when users view document properties. Professional documents should have accurate, complete information.
SEO and Accessibility
Search engines may use PDF metadata to understand document content. Proper titles and descriptions improve discoverability.
Privacy Concerns
Metadata can reveal sensitive information like author names, computer usernames, creation software, or editing history. Review metadata before sharing documents publicly.

Common Metadata Issues
Incorrect Author Names
Many PDFs inherit the computer username as the author. Edit this field to use proper names or organization names.
Revealing Software
The Creator and Producer fields show what software was used. This might reveal internal tools or software versions you'd prefer to keep private.
Outdated Information
Documents may retain metadata from earlier versions or template files. Review and update before distribution.
Metadata and PDF/A
PDF/A archival format has specific metadata requirements. When converting to PDF/A, ensure:
- Title is set (required)
- XMP metadata is properly formatted
- Creation dates are accurate
