PDF Page Count & Metadata Viewer

About this tool

The PDF Page Count & Metadata Viewer uses Mozilla's PDF.js library to read document information from a PDF file entirely in your browser. It displays the total page count as a badge plus a table with the file name, file size and every populated Info dictionary field it supports: title, author, subject, creator application, PDF producer, PDF format version, creation date and modification date. Empty fields are simply left out of the table, and an Encrypted badge appears next to the page count when the file carries PDF encryption. Each row has a Copy button for quick use in reports or documentation. Drop a PDF file or browse to select one — nothing is uploaded.

Why use it

• See a PDF's page count and metadata without opening Acrobat, Preview, or any desktop app

• Readable dates — raw D:YYYYMMDDHHmmSS strings are reformatted as YYYY-MM-DD HH:MM

• Copy buttons for every field — paste directly into reports

• Runs entirely in your browser via PDF.js — no server upload

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 as soon as the file is parsed
3. Read the file size, PDF version, and any populated title, author, creator or date fields
4. Click any 'Copy' button next to a field to copy that value to your clipboard
5. Drop another PDF to replace the report with that file's details

When it helps

• 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
• When checking which application created or produced a received PDF
• When extracting author or creation date information for record-keeping

Examples

Tips

• Some PDFs strip metadata for privacy — missing rows 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 will not open because it needs a password, use the PDF Unlock tool first
• 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.
