PDF Validation Tool

The tool analyzes a PDF to determine compliance with the PDF specification and conformance to PDF/A and PDF/UA standards. It is used by QA teams, compliance officers, and archival specialists to ensure long-term accessibility and regulatory readiness. It accepts standard PDF inputs and returns deterministic results independent of viewer software.

Core validation checks include structural integrity, header and cross-reference validation, font embedding presence, color space verification, image resolution analysis, and metadata completeness. Optional advanced checks cover full accessibility tagging conformance and extended metadata diagnostics. The output comprises an overall PASS/FAIL status, a conformance score (0–100), and a detailed per-check report that can be exported as JSON or PDF/CSV. The approach is deterministic and non-destructive; files are analyzed without modification, enabling repeatable audits and evidence gathering. Validation results are reproducible across identical inputs and can be augmented with a historical comparison between revisions. The validator also flags deprecated features, such as certain transparency models or unembedded fonts, and suggests remediation guidance.

Use cases include pre-submission verification for regulatory filings, archival ingestion for long-term preservation, and client-ready quality proofs for documentation deliverables. The tool differentiates itself through a weighted scoring model, clear error codes, and the ability to report in a structured, machine-readable format suitable for integration into CI pipelines and QA workflows. It supports enterprise workflows via JSON export and scriptable APIs, and its architecture is modular to ease integration with build pipelines and document management systems. Unlike generic validators, it emphasizes archival readiness and accessibility compliance.
