PDF translator
Turn a PDF into a bilingual book
Translate a PDF without losing the original: each paragraph comes back with its translation beside it, so you can read the book in two languages at once.
Als Gregor Samsa eines Morgens aus unruhigen Träumen erwachte, fand er sich in seinem Bett zu einem ungeheueren Ungeziefer verwandelt.
When Gregor Samsa woke one morning from troubled dreams, he found himself transformed in his bed into a monstrous vermin.
Er lag auf seinem panzerartig harten Rücken und sah, wenn er den Kopf ein wenig hob, seinen gewölbten, braunen, von bogenförmigen Versteifungen geteilten Bauch…
He lay on his armour-hard back and, when he raised his head a little, saw his domed brown belly, divided by stiff arching ribs…
»Was ist mit mir geschehen?«, dachte er. Es war kein Traum.
“What has happened to me?” he thought. It was no dream.
How it works
- Upload the PDF of a book, a story or a long document.
- Choose the second language from 68, and check the free preview of the opening pages.
- Translate it all, then read it side by side in the browser or download it.
Why keep the original
A translated PDF on its own asks you to trust every sentence. A bilingual one lets you check: read in the language you want, and look across when a line is unclear, a term matters or the original is simply better. For readers of two languages and for learners alike, that is the whole value of a parallel text.
What you get back
Paragraph-by-paragraph pairs
Each paragraph is matched with its own translation, not a page with a page, so you never hunt for the matching line.
PDF, EPUB and Kindle files
Keep it as a PDF, or take it as an EPUB, AZW3 or MOBI, which reflow on a small screen far better than a PDF does. See the e-reader guide for which file to use.
What works best
- Books and long-form text: novels, stories, essays, reports.
- PDFs with selectable text. Scans work too, if they are clean.
- Have the book as an EPUB? Use that instead: see bilingual EPUB.
Questions about bilingual PDFs
How do I translate a PDF and keep the original text?
Upload the PDF to DuoText and choose the second language. Instead of replacing the text, every paragraph is kept and paired with its translation, so you read both side by side.
Can I download the bilingual PDF?
Yes, as a PDF, and also as an EPUB, AZW3 or MOBI if you would rather read it on an e-reader, where the text reflows to fit the screen.
Does it work with scanned PDFs?
A PDF with selectable text gives the cleanest result. Scanned pages are read with text recognition, which depends on the quality of the scan; the free preview shows you how it turned out before you spend anything.
Does it keep the PDF's page layout?
It is built for books, so it keeps the text, chapters and headings and lays them out as a readable bilingual book, not as a copy of the original pages. For forms, slides or tables-heavy documents a layout-preserving document translator is a better fit.
