PDF Metadata Viewer
PDF Metadata Viewer reports pages, title, author, subject, creator, and producer through pdf-lib getters. It does not enumerate keywords, creation/modification dates, XMP packets, embedded-file metadata, signatures, annotations, page-level properties, hidden content, or forensic remnants. Blank results do not prove that a PDF contains no metadata.
Runs locally — files stay on your deviceDoes an empty viewer result mean the PDF is anonymous?
No. Only a small set of common fields is shown.
PDF can store metadata in several structures
The document information dictionary is only one source. XMP, attachments, signatures, annotations, forms, images, and external filenames can also reveal context.
How it works
The browser loads the PDF and calls getTitle, getAuthor, getSubject, getCreator, getProducer, plus page count.
Key concepts
Metadata is self-asserted
Fields can be missing, wrong, or deliberately forged.
Visible content can reveal more
Names, comments, and document history may appear in pages or annotations.
When to use it
- Inspect common document fields.
- Check producer/creator labels.
- Review a simple PDF before sharing.
When not to use it
- Do not use it as a full privacy audit.
- Do not infer authenticity from author or producer text.
- Do not expect XMP or attachment enumeration.
Worked examples

PDF with Author and Creator- Expected output
Those fields listed
Common info entries are readable.
Blank info dictionary
- Input
PDF- Expected output
Dashes
Other metadata may still exist.
Signed PDF
- Input
PDF with signature- Expected output
Signature not reported
The viewer does not inspect it.
Common mistakes
Trusting author identity
The field is editable. Correction: Use signature validation.
Calling the scan exhaustive
XMP and embedded objects are omitted. Correction: Use forensic PDF inspection.
Ignoring the filename
External filenames can disclose information. Correction: Review the full sharing workflow.
Best practices
- Treat fields as clues, not proof.
- Run independent metadata/security inspection.
- Review visible and embedded content.
