PDF Metadata Viewer

The PDF Metadata Viewer opens a PDF and lays bare everything in its document catalogue: the title, author, subject, keywords, creator, producer, and creation and modification dates, alongside a per-page size table showing width and height in points, millimetres, and inches with each page's rotation. Four summary stats lead with the page count, file size, encryption status, and whether the file carries any metadata at all. Loading is strict by design — the tool first attempts a normal pdf-lib load, and if the document is encrypted, a dedicated "Password-protected" alert explains that inspection is impossible without the password and even suggests decrypting with qpdf --decrypt. An educational footer clears up the point-versus-inch relationship (25.4 mm = 72 pt) and notes that dimensions shown are the media box before rotation. Because inspection is read-only and entirely client-side, confidential files never leave the machine. For SEO practitioners auditing PDFs attached to a site, print designers verifying bleed boxes, or developers debugging generated documents, this PDF properties inspector answers the "what is this file, really?" question without installing a desktop reader.

• Auditing metadata in PDFs served on a website before they are indexed.
• Verifying print specifications — page size and rotation — before sending files to a press.
• Checking whether a generated PDF carries the right author and keywords for document management.
• Confirming the creation and modification dates of a received contract.
• Debugging a PDF pipeline that produced unexpected page dimensions.
• Inspecting a vendor's PDF before approving it as a final deliverable.

• Check the Has metadata stat first — an empty catalogue is a common SEO gap in public PDFs.
• Read rotation alongside dimensions, since the media box does not rotate with the page.
• Use the millimetre column for print work and inches for US paper sizes.
• For encrypted files, follow the suggested qpdf --decrypt step before retrying.
• Record the producer field when debugging generation issues — it names the tool.

• The Encrypted stat reads no in green — a quick sanity signal.
• Use the mm column to spot non-standard page sizes at a glance.
• Compare Created and Modified dates to detect post-signature edits.
• The badges confirm the client-side nature and pdf-lib version.
