How We Validate PDFs
Our PDF validation system performs comprehensive analysis to ensure your documents meet industry standards and are free from structural issues.
Structure Validation
We analyze the internal PDF structure to verify object integrity, cross-reference tables, and document trailer. This ensures your PDF is properly formed and can be opened by any compliant PDF reader.
- Cross-reference table verification
- Object stream validation
- Document trailer analysis
- EOF marker detection
Standards Compliance
We check compliance with major PDF standards including PDF/A for archival, PDF/X for print production, and PDF/UA for accessibility.
- PDF/A: Long-term archival standard
- PDF/X: Print production standard
- PDF/UA: Accessibility standard
Metadata Validation
We extract and validate metadata fields including creation dates, modification dates, author information, and software used to create the PDF.
Privacy & Security
All validations are performed anonymously. We don't store your files permanently, and all data is encrypted during processing. Your PDF is automatically deleted after analysis.
