What is PDF/UA?
The ISO standard (14289) for accessible PDFs — tagged structure, alt text, reading order — so assistive technology can read them.
Does this guarantee legal compliance?
It verifies the machine-checkable rules. Full compliance also needs manual review — we state what we check, nothing more.
Is my file safe?
Files are transferred over an encrypted channel and auto-deleted within 24 hours, never used for AI training.
