Why to validate ePub format ebooks?

Apple’s iPad only accepts ePub format ebooks. Those ebooks need to pass the strict ePub validation requirements. At epubconversion.com we provide ePub Validator to validate your epub files.

EPUB is a globally accepted, free and open-ebook. The EPUB ebook format was purposely discovered to be a single format that publishers and conversion houses can use in-home, as well as for distribution and sale. EPUB is the file extension of an XML format for reflow-able digital books and publications.

Many times during an ePub conversion, the standards for ePub reflow-able digital books are not maintained and it causes error. To identify any such errors, the ePub validation tool was discovered. This tool identifies errors for the ePub book developer to eliminate, then creates the ePub format book to meet all standards. The ePub validation tool checks OCF container structure, OPF and OPS mark-up.
