Each check returns pass, warning, or fail status with detailed explanations. The tool helps ensure your documents are accessible to screen readers, comply with basic accessibility guidelines, and follow PDF best practices. Essential for creating inclusive documents.

Technical Guide

Combines pdf-lib and pdfjs-dist for comprehensive analysis. pdf-lib reads metadata (title, author, subject), page structure (count, sizes), and form fields. pdfjs-dist extracts text content to verify the document has selectable (non-image) text. Each check produces a pass, warning, or fail result with descriptive detail. File size is evaluated against thresholds (under 5MB pass, 5-20MB warn, over 20MB fail). Page size consistency is checked across all pages.
