Yes, Babylon latest version (12) can translate PDF files!
We suggest that you convert your PDF files into Word documents first, and then translate them using our Document Translation feature. That way the translation will be more accurate and will be returned to you with the same format.
If the document you are using is a scanned PDF, make sure it is non-protected and in good quality to ensure the best results.
If you wish to translate single terms from your PDF, you can use the Babylon click to translate any word that appears in your document, even if it is a scanned document!
