Microsoft Office Word is the most professional word proscessor, and Adobe is the original developer of pdf, although it can convert pdf to word or excel, one matue and professiona word to pdf converter would be a better choice,.
If I am correct then there are lots of tools are available online to convert the file to pdf. PDF is format is generally used by everyone for their official purpose. Last night I was learning for how to sign pdf because its a good feature and its very good to validate the document. I have learned this from https://techtiertips.com/sign-pdf-online-for-free.html and now I can easily do my work in the office and could send pdf with signature to the clients.
