PDF Page Count & Metadata Viewer

View the page count and metadata (title, author, dates, encryption) of any PDF file in your browser.

About PDF Page Count & Metadata Viewer

The PDF Page Count & Metadata Viewer uses Mozilla's PDF.js library to extract document information from a PDF file entirely in your browser. It displays the total page count, file size, and all available metadata fields including title, author, subject, creator application, PDF producer, PDF format version, creation date, and modification date. It also indicates if the document is encrypted. Each field has a Copy button for quick use in reports or documentation. Drop a PDF file or browse to select one.

Why use PDF Page Count & Metadata Viewer

  • Instant metadata extraction without opening Acrobat or another PDF app
  • Shows encryption status so you know if a password is required
  • Copy buttons for every field — paste directly into reports
  • Runs entirely in your browser via PDF.js — no server upload
  • Instant metadata extraction without opening Acrobat, Preview, or any desktop app
  • Shows encryption status so you know if a password is required before redaction or editing

How to use PDF Page Count & Metadata Viewer

  1. Drag and drop a PDF file onto the drop zone, or click 'browse' to select one
  2. The page count badge and metadata table appear immediately after parsing
  3. Click any 'Copy' button next to a field to copy that value to your clipboard
  4. An 'Encrypted' badge appears if the PDF has password protection
  5. Drag and drop a PDF file onto the drop zone, or click browse to select one
  6. Read the file size, page count, PDF version, and any populated info dictionary fields
  7. Look for the Encrypted badge — it appears if the PDF has any password protection

When to use PDF Page Count & Metadata Viewer

  • When verifying that a PDF's metadata is correct before distributing it
  • When auditing a batch of PDFs and need page counts quickly
  • When checking if a received PDF is password-encrypted
  • When extracting author or creation date information for record-keeping
  • When verifying that a PDF's metadata is correct before distributing it externally
  • When auditing a batch of PDFs and you need page counts quickly without opening each one

Examples

Word-exported PDF

Input: report.pdf created by Microsoft Word 2021

Output: 12 pages, Creator: Microsoft® Word for Microsoft 365, Producer: Microsoft® Word for Microsoft 365, PDF 1.7

Encrypted PDF

Input: secure-contract.pdf with owner password set

Output: Page count + Encrypted badge; metadata may be partial; use PDF Unlock first

PDF/A archive

Input: invoice-2024.pdf saved as PDF/A-1b

Output: 1 page, conformance level shown in metadata; suitable for legal long-term archive

Stripped metadata

Input: anonymous.pdf produced by a privacy-conscious tool

Output: Page count present, Title/Author/Creator empty — normal for privacy-stripped exports

Tips

  • Some PDFs strip metadata for privacy — empty fields are normal and not a tool error
  • The PDF date format D:YYYYMMDDHHmmSS is reformatted to YYYY-MM-DD HH:MM for readability
  • Producer often differs from Creator — Creator is the authoring app, Producer is the PDF library that wrote the file
  • If the file shows as Encrypted, use the PDF Unlock tool first before editing or extracting
  • PDF version 1.4 and below uses RC4-40 encryption; 1.5+ uses RC4-128; 1.7+ may use AES — affects unlock difficulty
  • Compare creation and modification dates to spot recently edited documents in a batch

Frequently Asked Questions

What metadata fields are shown?▾
Page count, file name, file size, title, author, subject, creator, producer, PDF format version, creation date, and modification date.
Does it work on encrypted PDFs?▾
It can read the page count and basic metadata from some encrypted PDFs. If the PDF requires a password to open, PDF.js may fail to parse it fully.
Is the PDF uploaded to a server?▾
No. PDF.js runs entirely in your browser. The file is read with FileReader and processed locally.
Why are some metadata fields blank?▾
Metadata fields are optional in the PDF specification. Many PDFs — especially those produced by converters — omit fields like title or author.
What date format are creation and modification dates shown in?▾
PDF dates are stored in the format D:YYYYMMDDHHmmSS. The viewer reformats them as YYYY-MM-DD HH:MM for readability.
Does this tool support password-protected PDFs?▾
Partially. PDF.js may be able to extract metadata without the password for some encryption modes, but full decryption requires the correct password (use the PDF Unlock tool).
What's the difference between Creator and Producer?▾
Creator is the authoring application (Word, InDesign, LaTeX). Producer is the library that wrote the PDF bytes (pdf-lib, Distiller, Ghostscript). They often differ.
