I have a few English PDF documents on my Android phone that I need translated into Kannada for my parents, but is there a way to do this directly on mobile without messing up the layout?
Honestly, the easiest way is the Google Translate app on Android, it can handle whole documents now and keeps the layout mostly intact. Just open it, tap the document option and pick your PDF. Fair warning though, Kannada text length differs from English so spacing can shift a bit. I see the same thing plotting drawings with translated notes.
