Could you use the expression in context? If you're saying e.g., "I got this pdf offline", I would argue your usage is incorrect and that saying, "I downloaded this pdf","got it online", or some variant would be more accurate. That is, unless you would consider, 'got it offline' to be an idiomatic expression for 'downloaded/retrieved-from-the-internet' in whatever region you're from. ~
