About:
EPUBCheck is the official reference tool and validation library for checking the conformance of EPUB publications against the EPUB specifications. It verifies the structure, content, and internal formatting of EPUB 2.0 and 3.0 files to ensure they meet industry standards for compatibility across reading systems.
Key Features:
  • Validates EPUB 2.0 and 3.x files for conformance
  • Detailed error reporting with line numbers and explanations
  • Command-line interface for automation and scripting
  • Java-based library for integration into other applications
Use Cases:
  • Automated quality assurance in publishing workflows
  • Debugging malformed EPUB files before distribution
  • Compliance checking for digital publishing standards
Alternatives:
  • Ace by DAISY – Focuses on accessibility auditing rather than strict spec conformance.
  • Kindle Previewer – Amazon-specific tool that checks compatibility for Kindle devices but not general EPUB spec validity.
