PDF to Accessible EPUB
for Libraries
Convert PDF collections to accessible EPUB3 for screen reader users, Overdrive, and accessible digital lending — without installing software on every workstation.
Convert a sample — free →Accessibility + Section 508
Output EPUB3 files include proper heading hierarchy, ARIA landmarks, alt text preservation, and logical reading order — meeting library accessibility requirements.
Screen reader ready
NVDA, JAWS, and VoiceOver navigate EPUB structure (headings, lists, tables) correctly. The semantic structure that screen readers need is built in.
No software to install
Browser-based. Staff can convert PDFs from any workstation without installing Calibre, Adobe, or any desktop software. Works on Windows, Mac, and Linux.
Scanned materials with OCR
Digitised special collections, historical documents, and scanned books are processed with automatic OCR before conversion — making them accessible for the first time.
Overdrive and Libby compatible
Converted EPUB3 files meet the format requirements for Overdrive, Libby, and other digital lending platforms used by public and academic libraries.
Patron privacy
Files are processed in isolated temporary storage and never retained. No patron document content is stored, logged, or used for any secondary purpose.
