How to View PDF Metadata
Why View Metadata
PDF metadata describes the document: title, author, producer, dates, and more. Viewing it helps with organization, audits, privacy checks, and understanding how a file was created or edited.
What You See
The viewer reads standard fields and shows the page count and file size. You can export everything as JSON for your records or automation. Key fields include:
- Title, Author, Subject, Keywords: Document-level descriptions often filled by the creating application.
- Creator: The application where the document originated (for example, Microsoft Word, LibreOffice, or a design tool).
- Producer: The library or driver that wrote the PDF file itself (for example, pdf-lib, Adobe PDF Library, or a browser's PDF engine).
- Creation and Modification Dates: When the PDF was first created and last saved.
- Page Count and File Size: Useful for planning printing, uploading, or sharing.
Common Use Cases
Use the PDF Metadata Viewer to:
- Check the author, software, and dates on documents you receive.
- Audit PDFs before publishing, filing, or client delivery.
- Verify whether a file matches its claimed origin (for example, a bank statement vs a design tool).
- Prepare for metadata cleanup by first inspecting what fields are present.
Privacy
Reading happens locally in your browser using WebAssembly, so the PDF is never uploaded to any server. You can safely inspect sensitive or confidential documents.
Limitations
This tool reads document-level metadata that the PDF exposes. It does not perform deep forensics such as revision history analysis, font mapping, or active content inspection. For those needs, use a dedicated PDF security or forensics inspector.
