How to Use PDF Info - Step by Step Guide
Step 1: Upload Your PDF
Upload your PDF file (up to 50 MB) by clicking the upload area or dragging and dropping the file into the browser. The tool accepts any valid PDF regardless of version, encryption status, or complexity. You can upload documents from your computer, downloaded email attachments, or files saved from other applications.
Step 2: Review Complete Analysis
Our engine analyzes every aspect of your PDF and displays results in organized, collapsible sections. The analysis begins automatically after upload and typically completes within a few seconds, even for large and complex documents. Each section focuses on a specific category of document properties so you can quickly navigate to the information you need.
Document Overview:
- File name and size (in bytes, KB, and MB)
- Page count
- PDF version (1.0 through 2.0)
- Linearized (Fast Web View) status — indicates whether the PDF is optimized for streaming delivery over the web
Page Analysis:
- Dimensions for each page (width x height) in points, millimeters, and inches
- Orientation (portrait/landscape) for every page
- Mixed page size detection — flags documents with inconsistent page dimensions
- Rotation values — shows any rotation applied to individual pages
Security:
- Encryption method and level (AES-128, AES-256, RC4)
- Permission settings (print, copy, edit, annotate, form fill)
- Password protection status (user password, owner password)
Metadata:
- Author, title, subject, keywords
- Creation and modification dates with full timestamps
- Creator application (the software used to author the original document) and PDF producer (the library or tool that generated the PDF)
Content Summary:
- Font inventory (names, types, embedding status — fully embedded, subset, or not embedded)
- Image count and types (JPEG, JPEG2000, CCITT, PNG-encoded)
- Form fields count and types (text fields, checkboxes, radio buttons, dropdowns)
- Annotations count (comments, highlights, stamps, links)
- Bookmarks count and nesting depth
Step 3: Export or Use Results
Download the complete analysis as a structured JSON file for programmatic use, or as a formatted plain text report for easy reading and sharing. You can also copy individual fields directly from the interface to paste into emails, reports, or ticket systems. The JSON export is particularly useful for integrating PDF analysis into automated quality-control workflows.
Why You Need This Tool
Prepress Verification and Print Readiness
Before sending a PDF to a commercial printer, you need to verify that every technical detail is correct. The PDF Info tool reveals whether all fonts are properly embedded (preventing font substitution on the printer's system), confirms page dimensions match the intended print size, checks that the PDF version is compatible with the printer's RIP software, and identifies the color spaces in use. Catching a missing embedded font or an incorrect page size before production saves reprints and delays.
Troubleshooting Problematic PDFs
When a PDF is not displaying correctly, fails to print, or causes errors during processing, the root cause is usually hidden in the document's internal structure. The PDF Info tool lets you diagnose issues by examining the PDF version, encryption settings, font embedding status, and page properties. A font that is referenced but not embedded will cause display issues on systems that lack that font. An unusual page rotation value can explain why content appears sideways. Identifying the PDF producer can reveal known compatibility issues with specific PDF generators.
Compliance and Regulatory Auditing
Many industries require PDF documents to meet specific standards. PDF/A compliance for long-term archival demands specific metadata fields, embedded fonts, and the absence of certain features. Accessibility standards (Section 508, WCAG) require tagged document structure. Corporate governance policies may mandate specific metadata (author, department, classification level). The PDF Info tool provides the data needed to verify compliance without opening the document in specialized and expensive software.
Security Assessment
Before distributing or archiving sensitive documents, you need to confirm that encryption and permission settings are correctly applied. The PDF Info tool shows the exact encryption method (AES vs. RC4), key length (128-bit vs. 256-bit), and granular permission flags. You can verify that a document prevents copying and editing while still allowing printing, or that a document intended for public distribution has no unnecessary restrictions.
Document Assessment Before Processing
Before running a PDF through any processing pipeline — merging, splitting, converting, compressing, or OCR — understanding its properties helps you choose appropriate settings and avoid unexpected results. Knowing the page dimensions, font types, image compression methods, and PDF version helps you select the right tool configurations and anticipate the output quality.
Quality Control for Submissions and Deliverables
When receiving PDFs from vendors, contractors, freelancers, or other departments, the PDF Info tool lets you verify that delivered documents meet your specifications before accepting the work. Check that page counts are correct, dimensions match requirements, fonts are embedded, and metadata is properly populated — all without installing any special software.

Common Use Cases
Print Production and Prepress Quality Control
Print shops and prepress operators analyze customer-submitted PDFs to verify that all specifications are correct before starting a production run. This includes checking that fonts are embedded (preventing substitution), page dimensions match the ordered print size, bleed marks are present where needed, and color spaces are appropriate for the printing method. Catching these issues before production prevents costly reprints and delivery delays.
IT Support and Help Desk Troubleshooting
Help desk and IT teams use PDF analysis to diagnose user-reported issues with PDF files. When a user reports that a PDF will not open, displays incorrectly, or fails to print, the IT team can examine the document's PDF version, encryption method, font embedding, and internal structure to identify the root cause. This is much faster than trial-and-error troubleshooting.
Legal Document Review and e-Discovery
Legal teams verify document specifications, metadata, and encryption settings during litigation and e-discovery processes. Metadata such as author, creation date, and modification history can be relevant evidence. Encryption and permission analysis confirms that documents are properly secured for confidential proceedings. Page dimensions and structure analysis ensures documents meet court filing requirements.
Publishing Quality Assurance
Publishers verify that manuscript PDFs meet production specifications before sending to layout or printing. This includes checking PDF version compatibility, font embedding, image resolution indicators, and overall document structure. The analysis helps catch issues early in the production pipeline before they become expensive problems.
Accessibility Auditing and Compliance
Organizations check document structure for accessibility compliance elements required by Section 508, WCAG, and other accessibility standards. The PDF Info tool reveals whether a document contains tagged structure, proper reading order markers, and the metadata fields that assistive technologies rely on.
Document Migration and System Integration
When migrating document repositories to new document management systems, IT teams assess PDF properties across large collections to identify compatibility issues, categorize documents by type and version, and plan migration strategies. The JSON export makes it easy to process analysis results programmatically across hundreds or thousands of documents.
Best Practices
Check Font Embedding Before Printing. The most common cause of printing problems is fonts that are referenced but not embedded. Always verify that all fonts show "Embedded" or "Subset" status before sending to print. If fonts are not embedded, use a tool like a PDF printer driver or editor to re-embed them.
Verify Page Dimensions for Every Page. Documents created by merging files from different sources often have mixed page sizes. The per-page dimension analysis reveals inconsistencies that could cause printing or display issues. Standardize page sizes using our Resize PDF tool before distribution.
Use JSON Export for Batch Workflows. If you regularly analyze PDFs as part of a quality-control process, download the JSON export and integrate it into your automated pipeline. The structured format is easy to parse and compare against specification templates.
Check Linearization for Web PDFs. PDFs published on websites should be linearized (Fast Web View enabled) so that browsers can begin displaying the first page before the entire file has downloaded. If the linearization status shows "No," optimize the file using our Optimize for Web tool.
Review Encryption Before Distributing. Before sharing sensitive documents externally, verify that the encryption method and permission settings match your security requirements. AES-256 is the current recommended standard for strong encryption.
