SiteList review score
BookTranslator makes book and document translation unusually easy to start. Real-user performance is slow, and clearer numeric pricing would make the buying decision easier.

Buyer questions
Questions buyers actually ask
How accurate is the AI translation?
BookTranslator translates with context rather than word-for-word replacement, so names, terms, and phrasing stay consistent across chapters. The AI understands paragraph-level meaning and tone, which makes long books read naturally. Upload your own book to see the exact price before checkout.
How much does it cost to translate a book?
The cost depends on the book's length. Pricing is based on word count, and you always see the final price before you confirm payment. Pay per task, buy one-time credits, or choose a Pro plan for monthly credits and lower rates.
How long does the translation process take?
Most standard files finish in minutes. Very large books or scan-heavy PDFs can take longer because they are processed in sections for quality. You'll be notified when the translation is ready, so you don't need to keep the page open.
Will my files be used to train AI models?
No. Your uploaded files and translation output are never used to train AI models. They are processed only to deliver your translation and related product features.
Will the book formatting and layout be preserved after translation?
Yes. Chapters, headings, tables, images, and page layout are preserved. The translated text is placed back into the original structure, so the result reads like a finished book rather than raw text.
Can you translate scanned PDFs?
Yes. BookTranslator includes OCR that extracts text from scanned pages and images inside PDFs, then translates the recognized text.
Which file formats do you support?
BookTranslator supports PDF, EPUB, DOCX, TXT, MOBI, Markdown, HTML, SRT subtitles, images, and more. 27+ file formats in total.
Is the translation good enough for publishing or professional use?
For reading, study, and business or personal documents, the quality is excellent. For professional publishing we recommend a review pass for domain-specific nuances. The translation gives you a clean, fully formatted draft to work from.
Can I try BookTranslator for free?
No. BookTranslator does not grant trial credits or provide a general free full translation. You can see the final price before checkout, then pay per task, buy one-time credits, or choose a Pro plan.
Do unused Pro monthly credits roll over?
No. Unused monthly credits from the current subscription cycle expire when the next cycle begins, then your new monthly credit allowance is added.
Can I get a bilingual output with both original and translated text?
Yes. On supported tasks, BookTranslator can provide a bilingual version in addition to the translated output. This is useful when you want to compare the original text with the translation for review, study, or QA. Bilingual availability can depend on the file type and workflow, so the exact download options may vary by task.
