Validation Checks
Cover Image Check
Required for publishing - Confirms a cover image is uploaded and properly configured. Professional appearance requires a cover.
Copyright ISBN Check
Publishing best practice - Checks if ISBN appears in your copyright section. Helps readers verify book authenticity.
Image Alt Text Check
Accessibility compliance - Ensures all images have descriptive alt text for screen readers and accessibility standards.
How Validation Works
Automatic scanning runs when you click Generate E-Book. Critical errors (ISBN, cover image) prevent EPUB creation, while warnings (copyright ISBN, alt text) allow generation but suggest improvements.
Fix any errors before generating - use the Book Metadata screen to add missing ISBN or cover image.
Next Steps
After all checks pass, your EPUB generates successfully. See Exporting EPUB Files for details about the final file.
