About PDF Health Checker

PDF Health Checker is a unique diagnostic tool that analyzes your PDF file for potential issues and provides optimization recommendations. Unlike simple PDF viewers, it goes deep into the document structure to identify problems that could affect viewing, printing, or sharing.

The analysis covers multiple aspects of your PDF including file integrity to detect corruption, font embedding status to ensure text displays correctly on all devices, image optimization opportunities to reduce file size, accessibility compliance for screen readers, metadata completeness, and security settings.

This tool is invaluable for anyone who creates or distributes PDF documents professionally. Designers can verify their PDFs are print-ready, developers can ensure their generated PDFs meet standards, and businesses can check that their documents are accessible and optimized.

The health report provides a clear score for each category along with specific, actionable recommendations. Many issues can be fixed directly using other AuraPDF tools — the report includes direct links to relevant tools for quick fixes.

PDF Health Checker is completely free and unique to AuraPDF. No other online PDF tool offers this level of document analysis. Your files are processed securely and deleted automatically within 30 minutes.
