Accessibility remediation for EPUB and PDF
The ADA Title II deadline passed in April 2026, and the European Accessibility Act has been in force since June 2025, so an inaccessible backlist is now a legal liability. We turn legacy PDFs and EPUBs into certified, compliant files without re-authoring a single page.
- Standards
- WCAG 2.2 AA, EPUB Accessibility 1.1, PDF/UA-1, Section 508, EAA
- Formats
- EPUB and PDF, remediated as they are
- Reports
- DAISY Ace for EPUB; PAC 2026 and VeraPDF for PDF
