Meet PDF Auditor
PDF Auditor helps you inspect PDF internals instead of only viewing page contents. It is useful when you need to understand metadata, security settings, embedded files, JavaScript, annotations, accessibility tags, size composition, or suspicious document structure.

Unlike a standard PDF editor, PDF Auditor is built for inspection. It helps you answer what is present in a document, where it appears, and which structures deserve closer review.
Who it is for
PDF Auditor is designed for IT professionals, security analysts, document specialists, digital publishers, QA teams, and anyone reviewing documents before distribution or archival.

How to read results
PDF Auditor reports structure, properties, and risk signals. A finding means something deserves review; it does not automatically mean the PDF is malicious, invalid, legally unsafe, or fully accessible.
What it does not do
PDF Auditor is not a PDF editor and does not replace expert security, legal, or forensic review. Treat findings as signals to investigate and verify.
