Extract PDF Metadata Online for Free
Need to inspect a PDF's document properties? IronFreeTools' Extract PDF Metadata tool reads standard metadata and page details directly in your browser.
Metadata helps identify how a PDF was created, who authored it, when it was produced, and how its pages are structured. Exporting that data is useful for audits, filing, automation, and troubleshooting.
Common Use Cases
- Audit document titles, authors, and creation dates
- Check page count and page sizes before processing
- Inspect producer and creator fields for troubleshooting
- Export metadata for records management
- Verify page rotation before printing or conversion
How It Works
Upload a PDF and the tool reads standard document metadata plus page-level size and rotation details. The result downloads as JSON. For developers building .NET document workflows, IronPDF's metadata features provide programmatic access to PDF document properties.
Tips for Best Results
- Unlock password-protected PDFs before extracting metadata
- Expect some fields to be empty if the original PDF did not define them
- Use the JSON output when you need structured data for automation
