PQ PDF is a privacy‑first PDF security suite with 45 tools. It combines 20+ static, dynamic, ML, and differential‑parsing engines to analyze PDFs for exploits, scripts, obfuscation, and structural anomalies. Beyond threat scanning, PQ PDF includes tools for structure inspection, metadata review, object diffing, and safe transformations, so engineers and security teams can actually understand what a PDF is doing, not just get a green checkmark.
