FAQ

Can a PDF fully "pass WCAG"?

No static tool can honestly claim that — several criteria need human judgment. Preflight verifies the determinable ones and explicitly lists what it did not evaluate.

Which standards can I select?

WCAG 2.1 and 2.2 (A/AA/AAA), PDF/UA-1 and PDF/UA-2, plus Section 508 and EN 301 549 profiles.

What happens to my documents?

Uploads are tenant-scoped, encrypted at rest, and anonymous uploads auto-purge within 24 hours. Result pages are token-gated and never indexed.
