PDF/UA Scanner
Upload a PDF to check its real PDF/UA tag structure and estimate remediation effort. Table structure and per-image alt text require full content-stream parsing and are flagged for manual review rather than guessed.

What This Scanner Checks
Real Tag Tree
Whether the document has an actual /StructTreeRoot, not only the /MarkInfo/Marked flag. A document can claim to be tagged without a real structure tree.
Heading Order
Whether tagged headings (H1, H2, H3...) follow a logical, non-skipping order.
Figure Alt Text
How many tagged Figure elements are missing alternative text.
Table Header Cells
How many tagged Table elements are missing TH header cells for screen reader navigation.
Title & Language Metadata
Whether the PDF's /Title and /Lang document properties are set.
