EPUB Translator

An EPUB is a reflowable ebook package containing chapters, navigation, images, links, and text styles.

Yes. Upload the .epub here and pick English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish or Portuguese. You get back an EPUB with each original paragraph followed by its translation.

Books are counted in pages of 500 words, so a 100,000-word novel is 200 pages. The first 3 pages each day are free; after that come your plan's bonus pages and any voucher code, then 5 credits a page on Fast or 10 on Standard.

Up to 200 pages, which is 100,000 words, and 50 MB. Split a longer book into volumes and translate them one at a time.

Your uploaded EPUB and its translation are deleted from our servers within 24 hours, so download the translated book the same day.

OpenImmersive Translator · PDF translates a PDF while keeping the original layout, in one of two modes. Document mode, for reports, manuals and contracts, outputs English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, Portuguese, Turkish, Russian or Ukrainian for PDFs of up to 200 pages. Academic paper mode keeps equations, figures and references where the author put them and outputs Simplified Chinese for papers of up to 40 pages.

Yes. Choose English under "Translate into" and upload the PDF. The source language is detected for you — Chinese, Japanese, Spanish, French, German and many more — and the English PDF keeps the original layout. If the document is already in English, nothing is charged and you are asked to pick another output language.

Here, PDF and EPUB. A PDF comes back as a PDF; an EPUB comes back as a bilingual EPUB, with the translation under each paragraph. Word (DOCX), PowerPoint (PPTX), Excel (XLSX), TXT, Markdown and SRT files are translated on the main OpenImmersive Translator site, which also covers every target language.

For PDFs, pay for this file at Fast $0.10/page or Standard $0.20/page, minimum $3 on the unpaid remainder, or buy $10/1,000 credits (about 200 Fast or 100 Standard pages). Neither requires an account. Stripe Checkout collects your email for the receipt, credit code and translation link. Free pages and existing balances are deducted first. Old page vouchers remain valid; new page packs are no longer offered for PDFs.

Your transactions and payment details are securely handled by our payment provider using advanced encryption technology and strict adherence to banking industry standards. Your credit card information is sent directly to the bank, and OpenImmersive Translator does not access or store any payment information, ensuring your payment security.

The first 3 pages a day are free. Existing plan pages, voucher balance and account credits are applied before payment. A PDF page uses 5 credits on Fast or 10 on Standard. You can pay for an uncovered PDF remainder without registering. Registration grants 100 credits usable across the site. Guest credit codes are for documents; verify your email to transfer their remaining balance into an account.

For paid PDFs, the receipt and private order link are emailed to the address collected at Stripe Checkout. A download link is emailed when translation finishes, even if you close the page. The file and link expire no later than 24 hours after upload; payment and email delivery do not extend this deadline. Free translations can be downloaded from their result page.

If a single-file PDF translation fails, its payment is refunded and reserved balances are returned. If a credit-pack-funded translation fails, consumed credits are returned to the code and the purchased pack remains available. Other refunds are subject to applicable law.
