Upload your book file. Wait exactly one minute. BookTranslator spits out a complete translation that actually reads like the author intended. No choppy machine translations that miss storytelling nuance.

The speed hits differently when you've waited weeks for human translators before. One click handles your entire EPUB or PDF. Side-by-side comparison lets you check the original against the translation — handy when context feels unclear.

A linguistics professor preparing course materials would find this useful. Upload that untranslated German novel for your comparative literature class. Readable English text ready for students in sixty seconds.

BookTranslator handles 77 languages across multiple file formats. DOCX works fine. TXT too. Even subtitle files like SRT. The 50MB file limit covers most books without issue, though massive academic texts might need splitting.

Your translation history sticks around permanently with the Pro plan at $8 monthly. Free users get 1,000 credits and 30 days of saved history. Guest payments work per task but your files disappear after a week — annoying if you're translating regularly.

BookTranslator throws 1% of Pro subscriptions toward carbon removal through Stripe Climate. They don't mention data handling specifics on their site, so you're trusting them with whatever documents you upload. Most people won't care about the environmental angle, but the translation quality and speed make it useful.

Frequently asked

7 questions
How accurate are BookTranslator's translations compared to human translators?
BookTranslator's all about keeping the story flowing -- not giving you choppy robot text. It won't beat experienced human translators who can adapt cultural stuff and get creative with interpretations. But it's built for speed and readability, not literary perfection.
What's the maximum file size BookTranslator can handle?
You're capped at 50MB uploads. That covers most regular books just fine. Huge academic texts or books packed with images might hit that wall though -- you'd need to split them up first.
Do my translated files stay saved permanently with BookTranslator?
Pro subscribers ($8/month) keep everything forever. Free users get 30 days before files vanish. Guest payments? Just one week -- super annoying if you translate stuff regularly.
Can BookTranslator handle subtitle files and document formats besides books?
Yep! It does SRT subtitle files plus DOCX and TXT documents. Don't let the name fool you -- you're not stuck with just EPUB and PDF books. All 77 languages work across these file types.
How does the credit system work for free BookTranslator users?
Free accounts start with 1,000 credits. The site doesn't spell out exactly how credits get used per translation or file size though. Your stuff disappears after 30 days on free plans -- Pro users skip the credit hassle entirely.
Which languages does BookTranslator support for translation?
77 different languages total. You can go from any of these to any other one. They don't list them all on the main site, but it's got major world languages plus tons of regional ones.
How long does BookTranslator actually take to translate a full book?
One minute flat -- doesn't matter how long your book is. Pretty wild when you've waited weeks for human translators before. That's assuming your file fits their size limits, of course.
