How to translate a PDF in Google Translate.
If you have a PDF file such as an eBook or a document from a foreign client that you would like to translate to your native language, the best way to do that is using a human translator. However, if you need to use something online, you can follow these instructions to translate a PDF file in Google Translate.
Access the Translate Document tool.
Choose the language you would like to translate from and to. If you’re not sure what language your PDF file is in, you can set the input language to “Detect language.”
Click Choose File and then the blue Translate button.
Google will then translate the text.
You will get a pop-up with the PDF file translated.
