What Is a PDF Analyzer?
A PDF analyzer reads the internal structure of a PDF file and extracts detailed information including page count, document metadata, and text statistics. Upload a PDF to instantly preview its contents and get a full breakdown. This tool runs 100% in your browser — your files are never uploaded to any server.
It supports drag-and-drop upload, in-browser PDF preview, metadata extraction (title, author, version, dates, page size, encryption status), and text statistics (words, characters, sentences, paragraphs, table detection).

Features Explained
In-Browser PDF Preview

The tool renders every page of your PDF directly in the browser using pdf.js. You can scroll through the full document without leaving the page.
Document Metadata Extraction
▼
Extracts and displays comprehensive PDF metadata: document title, author, subject, keywords, creator application, PDF producer, PDF version, creation and modification dates, page dimensions with standard size detection (A4, Letter, etc.), and encryption status.
Text Statistics

Analyzes all text content in the PDF and reports word count, character count (with and without spaces), sentence count, paragraph count, and whether tabular data was detected.
Drag-and-Drop Upload

Drag a PDF file from your file explorer and drop it onto the input area. The drop zone highlights when a file is dragged over it.
Standard Page Size Detection
▼
Automatically identifies standard page sizes like A3, A4, A5, Letter, Legal, and Tabloid, and reports the orientation (Portrait or Landscape).
Encryption Detection
