Procedure
Step by step
Upload the PDF
The server validates the file and applies structural rules. When available, pinned veraPDF validation provides an independent machine signal.
Read findings by status
Passed means the available machine evidence supports the check. Failed means a detectable issue was found. Needs review means a person must decide.
Use the result to plan work
Prioritize blocking structural issues, then schedule manual review for content and behavior that automation cannot verify.
Choose a remediation path
Use DocAccessible for editable HTML and rebuilt PDF output when reflow is acceptable, or request qualified manual remediation when the original layout must be preserved.
What the checker does not prove
A checker result is not certification. It cannot fully determine reading experience, visual meaning, complex tables, forms, or whether alternative text fits the document's purpose.
