The EPUB output mode determines what text you read after translation. Choose it before submitting the task, then check the downloaded edition rather than assuming a filename or cover identifies the mode.
PDF Craft offers translation-only and bilingual EPUB output. Both are reading files; neither requires installing the desktop app to complete the online task.
Know what each mode contains
Translation-only replaces the original text with the translation. It is useful when you want to read continuously in the new language and consult a separate original only when necessary.
Bilingual keeps each original passage followed by its translation. It makes local comparison easier, but adds more text to the reading sequence. It is not a synchronized two-column display or a promise that corresponding sentences always fit on one screen.
For the reasons to choose one reading style over the other, see bilingual EPUB versus translation-only reading. This guide focuses on setting and checking the output.
Make the selection in the actual task
- Open the EPUB translator and upload the complete usable EPUB.
- Choose the target language in the task settings.
- Choose translation-only or bilingual output from the offered modes.
- Add concise subject, name, terminology, or tone instructions if needed.
- Review the language, mode, and current limits before submitting.
The landing-page URL does not choose those task parameters for you. EPUB input requires translation, while PDF-to-EPUB and PDF-to-Markdown allow conversion without translation. If you start from a PDF, check that distinction separately.
Do not infer that every format offers the same modes. The current PDF output workflow is a translation-only replacement route; the bilingual EPUB description is not a promise of bilingual PDF export.
New users receive trial credits and translation is charged by usage. Check Pricing for current rates rather than assuming an additional task or changed output has no cost.
Understand length and file-size effects
A bilingual edition contains both languages, so it generally requires more reading space. That does not mean its byte size or page count will double exactly. Images, fonts, packaging, language length, and reader settings all affect those measures.
A short dialogue exchange may be easy to compare. A long original paragraph can fill several screens before the translation appears. Test a representative passage at the font size and screen width you use for reading.
Translation-only removes the alternating-language text, but you should still keep the original EPUB. It remains useful when you encounter a doubtful term, a confusing pronoun, or an important quotation.
Identify the downloaded edition clearly
Download from the completed task and save under a recognizable filename, such as book-english.epub or book-original-english.epub. Keep the source separately. Identical covers and titles can hide the fact that you opened an older result.
Open a known passage and verify the language arrangement. In bilingual output, check a short paragraph, a heading boundary, and a passage around an illustration or note. Do the original and translated text follow in the expected order?
Then check chapters and navigation. Output mode is only one part of a usable EPUB; a correct mode does not establish that all content, links, and images are correct. The format-preservation guide gives the wider review.
Fix the right kind of problem
If the book contains both languages but reading feels slow, the mode may be functioning as selected while not fitting your preference. Consider a translation-only edition for continuous reading and a separate comparison copy on a larger screen.
If passages are missing, out of order, or unreadable, inspect the source and another EPUB reader before treating it as a mode-choice issue. Follow the troubleshooting guide to separate download, file, and display problems.
Do not overwrite the only downloaded copy while investigating. Keep the original, result, and task reference so you can identify what was selected and what the reader actually displayed.
