Why Choose Free PDF Translator (No Signup Required)
Why do you need an online PDF translation tool? PDF documents cannot be edited directly, copy-paste translation is inefficient, and scanned PDFs are almost impossible to process. Many PDF translation tools require registration, login or even payment, and the threshold for use is high. Our free PDF translator allows you to translate PDF documents online without registration, and do it all directly in your browser.

Translate scanned PDF files with OCR built in
A scan has no text layer, so the page has to be read before anything can be translated. That step runs automatically here: upload the scan and translate scanned PDF to English or any supported language, with tables and columns recognised instead of flattened into one stream.
- Translate scanned PDF files without running OCR as a separate step
- Photographed pages and image-only PDFs are handled the same way
- Tables, columns and paragraph structure are recognised, not flattened
- Mixed files work too, where only some of the pages are scans
A scan is no longer the reason a PDF cannot be translated.
