One file at a timeA good translation pays attention to context and detail.
After EPUB translation, chapters, navigation, images, and reading flow should stay as intact as possible. What you get back should still feel like a complete ebook, not a pile of disconnected translated passages.
Keep the context
Translation considers nearby text to help carry the meaning from one passage to the next.
Read both languages
Bilingual EPUB places the translation after the original passage, making it easier to check important details.
Specify names and terms
Provide preferred translations for technical terms, names, and expressions before you begin.
Keep the book together
Chapters, navigation, images, and reading structure are preserved where possible, with checks for structural errors.
Common questions
Find answers about formats, results, and pricing.
What should I prepare?
Use an EPUB you are authorized to process and choose the intended target language. Keep the original book for comparison when checking the translated text.
How do I review a translated book?
Compare selected passages with the source. Check names, terminology, chapter order, links and notes. A readable translation still needs review where precise wording matters.
Does translation guarantee publication quality?
No. Automated translation can misunderstand context or use inconsistent terms. Review important passages with someone who understands both languages before publishing or relying on the result.
Where can I find prices and API availability?
See the pricing page for current translation charges. The public API documented here covers PDF-to-Markdown and PDF-to-EPUB conversion; do not assume it also provides EPUB translation.

Guide updated
How do you check both meaning and reading structure?
| Review target | What should you compare? |
|---|---|
| Content: meaning and terminology | Compare passages containing names, technical terms and long sentences with the source. Check negation, conditions, numbers and units, and note inconsistent translations of the same name. Fluency is not a substitute for checking meaning. |
| Structure: chapters and navigation | Open the translation in your intended reader and check the contents, chapter order, links and notes. Change the text size and inspect longer paragraphs. Keep the source and affected locations if text is missing or navigation fails. |
What should you do before using a translated book?
- Prepare a book you are authorized to process, confirm the target language and keep the original EPUB. Note preferred names and important terminology as a reference for your review.
- Follow the actual task status after submission. Processing completion does not mean the translation has been reviewed. Compare matching versions of the source and translated books so chapter and note differences are meaningful.
- Sample important passages and reading structure before deciding how much bilingual review is needed. Check context and correct errors in material you intend to quote, publish or use for important decisions, and keep a record of corrections.
What are these format descriptions based on?
The W3C EPUB 3.3 specification defines EPUB as a distribution and interchange format for digital publications. It describes packaging and reading structure; it does not certify the OCR or translation quality of a conversion tool.
