PDF Metadata Viewer
A PDF metadata viewer reveals the standard document properties that ordinary page view does not show. Inspect the title, author, subject, keywords, creator, producer, creation date, modification date, and page count, then download those results as structured JSON. This read-only check runs locally in your browser, so the PDF is not uploaded or changed.

Verified behavior and practical limits
Last tested:
How it processes your file
The browser reads the PDF document information dictionary and exports its standard fields and page count as JSON without changing the source file.
Verified behavior
- Reads title, author, subject, keywords, creator, producer, creation date, and modification date.
- Reports the document page count in the same JSON output.
- The operation is read-only and runs locally in the browser.
Important limits
- The viewer reports standard document information fields; it does not decode every custom metadata object or attachment.
- An empty result means those standard fields are absent, not that the PDF contains no other identifying content.
Reproducible example workflow
- Input
- A PDF received from an outside vendor.
- Action
- Run View Metadata and open metadata.json.
- Expected output
- A structured list of the standard properties and page count for review.

Frequently asked questions
What metadata does a PDF contain?
Typical fields include title, author, subject, keywords, the software that created and produced the file, and timestamps for creation and last modification.
Why is the output a JSON file?
JSON is structured and machine-readable, making it easy to archive metadata, diff it between document versions, or feed it into scripts and compliance tooling.
Does the tool modify my PDF?
No. View Metadata is strictly read-only — your original file is untouched, and only the extracted metadata is downloaded as a separate JSON file.
