What Makes EPUB Translation So Challenging?
In the digital reading era of 2026, EPUB remains the dominant eBook format. Yet for many translation tools, it's still a "tough nut to crack."
- Code Embedded in Text: EPUB is essentially a compressed package containing HTML and CSS. Traditional tools often break these tags, resulting in eBooks that won't open or have broken table of contents.
- Layout Corruption: Many online tools destroy the carefully designed image layouts and font styles after translation.
- Lack of Context Awareness: Common translation engines, without contextual understanding, can turn literary masterpieces into "instruction manuals."
To address these pain points, Belin Doc has developed a proprietary "Structure-Preserving Parser" that ensures text translation without touching any underlying code.
