PDF Page Count & Metadata Viewer

About this tool

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 it

• Instant metadata extraction without opening Acrobat or another PDF app

• Shows encryption status so you know if a password is required before redaction or editing

• 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

How to use

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. Read the file size, page count, PDF version, and any populated info dictionary fields
6. Look for the Encrypted badge — it appears if the PDF has any password protection

When it helps

• When verifying that a PDF's metadata is correct before distributing it externally
• 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 auditing a batch of PDFs and you need page counts quickly without opening each one

Examples

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

Glossary

PDF Info Dictionary

A standard PDF metadata structure with optional fields (Title, Author, Subject, Keywords, Creator, Producer, CreationDate, ModDate) — the source of most data shown by this tool.

Creator

The application that originally created the document content — for example Microsoft Word, Adobe InDesign, or LaTeX.

Producer

The library or application that wrote the actual PDF bytes — for example Distiller, pdf-lib, Ghostscript, or wkhtmltopdf. Often differs from Creator.

PDF/A

An ISO archival profile of PDF that forbids external dependencies and ensures long-term reproduction. PDF/A documents include conformance metadata in their XMP.

Encryption

Optional PDF feature using RC4 or AES to require a password for opening or to restrict actions like printing and editing.

PDF Version

The PDF specification version a file conforms to (1.4, 1.5, 1.6, 1.7, 2.0). Higher versions support more features (transparency, AES, attachments).

PDF.js

Mozilla's open-source JavaScript PDF rendering and parsing library used in Firefox and many web tools — runs entirely in the browser.

Page Tree

The hierarchical structure inside a PDF that organizes pages and lets viewers count, navigate, and render individual pages efficiently.
