About PDF Info

PDF Info reads the structure of a PDF and reports its page count plus document metadata — title, author, creator, and similar fields — as clean JSON. Reach for it when you need to confirm how many pages a file has, who or what produced it, or feed those numbers into a script. The PDF is parsed locally in your browser, so nothing is uploaded to a server.

Common uses

  • Confirm a downloaded contract is the full 47 pages before signing, without opening a heavy PDF viewer
  • Audit who authored a PDF by reading the Author and Creator metadata fields
  • Get a machine-readable page count to drive a downstream Split PDF or Extract PDF Pages step
  • Spot PDFs that still carry an old draft title in their metadata before sending them to a client
  • Check the producer string to tell whether a file came from Word, InDesign, or a scanner
  • Batch-triage a folder of PDFs by quickly pulling page counts one at a time

Frequently asked questions

What does the output look like?

A JSON object with the page count and any metadata fields the PDF declares, such as title, author, subject, creator, and producer. Fields that the document does not set are simply absent.

Does it read the actual text inside the PDF?

No. PDF Info reports structural data and metadata only. To pull the body text, use PDF to Text instead.

Is my PDF uploaded anywhere?

No. The file is parsed entirely in your browser. It never leaves your device, which makes it safe for confidential documents.

Is there a file-size limit?

There is no hard cap, but very large PDFs use more browser memory. Because only the structure is read rather than every pixel, even big files report their info quickly.

Can it tell me if a PDF is encrypted?

If a PDF is password-protected you will generally need to decrypt it first with Decrypt PDF before the metadata can be read.

Extract PDF Tables
