Free AI PDF Translator
Upload a PDF and the AI reads it — using OCR when the pages are scanned images — and translates the entire file into any of 450+ languages. Long PDFs keep consistent terminology from the first page to the last, and the result is clean translated text you can read online, copy, or download as a new PDF or HTML file. No signup required.
How to translate a PDF
- 1
Upload your PDF
Drag and drop the PDF into the translator above, or click to choose a file. Text-based and scanned PDFs both work — scanned pages are read with OCR.
- 2
Pick the target language
Choose the language you want from 450+ options. The language of your PDF is detected automatically, so you don't need to know what it's written in.
- 3
Read or download the translation
The AI translates the entire PDF — every page, not a snippet. Read the translated text online, copy it, or download it as a new PDF or HTML file.
What kind of PDFs can you translate?
Scanned documents
Scans of letters, certificates, contracts, and old records are read with OCR before translating — a scanned PDF works as well as a digital one.
Books & long PDFs
A book-length PDF translates end to end, chapter by chapter, with names and technical terms kept consistent throughout.
Papers & manuals
Research papers, user manuals, and official forms — upload the PDF and read the whole thing in your language, with the technical vocabulary translated consistently.
PDFs in 450+ languages
From a Spanish PDF to English or an English PDF to Japanese — and beyond, into historical languages like Latin and Ancient Greek that other PDF translators don't offer.
Scanned PDFs work too
A scanned PDF is just pictures of pages, so the translator runs OCR first: an AI vision model finds the text, reads it in place, and passes it on for translation. It copes with angled scans, older print, and decorative fonts better than traditional OCR. If what you have is a photo (PNG or JPG) rather than a PDF, the image translator does the same job for single pictures.
Translate a PDF to popular languages
Upload your PDF and translate it into any of the world's most-spoken languages.
Translate PDFs other tools can't read
Most PDF translators stop at mainstream languages. Polytranslator covers 450+, including ancient and historical ones — Latin, Ancient Greek, Old English, Coptic, Aramaic, and more. A digitized manuscript, a scan of a classical text, or an old family record can be translated into your own language, even when no mainstream tool recognizes the writing.

PDF translation FAQ
- How do I translate a PDF file?
- Upload the PDF in the translator above, pick a target language, and start the translation. The text is extracted — with OCR if the PDF is scanned — and the AI translates every page. Then read the translation online, copy it, or download it as PDF or HTML.
- Can I translate a scanned PDF?
- Yes. Scanned PDFs are pictures of pages, so an AI vision model performs OCR to read the text before translating. Clear scans work best, but angled pages, older print, and unusual fonts are usually handled well.
- Will the translated PDF look like the original?
- The translation is delivered as clean, readable text that follows your document's structure — headings and paragraphs — not a pixel-perfect copy of the original layout. You can download it as a fresh PDF or HTML file.
- Can I translate a whole book in PDF form?
- Yes. Long PDFs are split into chapters behind the scenes and translated with consistent terminology throughout. The biggest files need a Pro plan, which raises the limits to 20MB and 100,000 characters per document.
- Is the PDF translator free?
- Yes. PDF translation is free with a daily limit and no signup required. Sign in for a higher limit, or upgrade to Pro for unlimited daily documents and the largest files.
- Is my PDF stored or shared?
- Your PDF is used only to produce your translation. Uploads are never shared or made public, and are automatically deleted from our servers after at most 90 days.
