Validate PDF/A Compliance
Heuristic PDF/A-readiness audit — checks structural elements (XMP claim, MarkInfo, OutputIntent, tagged structure) and lists what would block strict validation.

How does the Validate PDF/A Compliance work?
Audit a PDF for PDF/A archival readiness. The tool inspects the structural elements every PDF/A validator looks for: XMP pdfaid claim (which level if any), OutputIntents array (declares the colour space), MarkInfo /Marked flag (tagged structure for 1A), StructTreeRoot presence, document /Lang attribute, title metadata, and encryption status (PDF/A forbids encryption). Failures and warnings come with remediation hints pointing to specific tools that can fix them. This is a HEURISTIC check — for certified validation, run veraPDF (open-source) or a commercial pre-flight tool on the file.

Convert a PDF to the PDF/A archival format (best-effort PDF/A-1b / 2b / 3b) by embedding the required metadata and conformance markers.
Walk a tagged PDF's structure tree, list every heading (H1–H6) in document order, and flag broken hierarchy (skipped levels, multiple H1s, missing H1).
Check whether a PDF is tagged (has a structure tree), how many tags it has, and whether key accessibility prerequisites (lang attribute, MarkInfo) are set.
Compare a PDF's structure-tree reading order against the visual top-to-bottom layout of its content. Flag pages where the tag sequence diverges from visual order.
Convert between Roman numerals and Arabic integers (1–3999). Strict subtractive-form validation — flags malformed numerals like IIII or VC.
