Why EPUB files break in generic translators
An EPUB is a packaged publication—not a flat document. Pulling out the prose is easy; returning a working ebook is the hard part.
Keep the package connected
A working EPUB combines XHTML chapters, CSS, a navigation document, metadata, a manifest, fonts and images. Bluente translates the language-bearing content while keeping those relationships intact.
- Chapter breaks remain chapter breaks
- Table-of-contents links continue to resolve
- Images remain anchored to the correct content
