I am a researcher who does not understand the Latin language. Sometimes I need to translate a full journal paper from Latin to the English language. I tried several websites such as Google, Bing, Yandex, and Translateking to translate Latin to English. There are several drawbacks with these online translators such as we cannot translate the full documents or pdf files. Sometimes, it does the imperfect translation. Can somebody suggest a good tool to translate a full document with higher accuracy?
Let me write as an answer what was already given in the comment: There is no such tool.
The automatic translation tools are very unreliable with Latin. We have previously explored the case of Google Translate with Latin, and no tool appears to do much better.
The conclusion is: If you need to understand a complicated document written in Latin, you need a person who understands Latin. That person can be you or someone else, but human work is needed, and the machine translation can well be completely useless to that human. There is no shortcut.
