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 →Output EPUB3 files include proper heading hierarchy, ARIA landmarks, alt text preservation, and logical reading order — meeting library accessibility requirements.
NVDA, JAWS, and VoiceOver navigate EPUB structure (headings, lists, tables) correctly. The semantic structure that screen readers need is built in.
Browser-based. Staff can convert PDFs from any workstation without installing Calibre, Adobe, or any desktop software. Works on Windows, Mac, and Linux.
Digitised special collections, historical documents, and scanned books are processed with automatic OCR before conversion — making them accessible for the first time.
Converted EPUB3 files meet the format requirements for Overdrive, Libby, and other digital lending platforms used by public and academic libraries.
Files are processed in isolated temporary storage and never retained. No patron document content is stored, logged, or used for any secondary purpose.
For large collections, the toolkit.bot API allows batch conversion from any programming language or automation tool — no per-seat licensing, no vendor lock-in.
