One of the top options is the PDF Translator & Editor. It can convert many file types, including native and scanned PDFs, Word, Excel, PowerPoint and images, into 136 languages. It uses Google and Microsoft's Neural Machine Translation models to perform accurate language identification and preserve formatting and layout, so it's good for people who need high-quality translations with a minimum of editing.
Another top option is O.Translator, which uses AI to translate documents in many file formats. It supports more than 60 languages and has a context-sensitive translation engine. O.Translator also prioritizes data security with Google's protected storage and has pay-by-the-page pricing, so it's good for individuals and businesses.
