Is there any Compression Technique for Video, Audio,Images & Documents in Xamarin Forms

I want to upload the audio, video and image files to the server. So I need to compress the files so it can easily be transported over the server.
FFMpeg(3rd party tool) was an option, but it is not supported in .net Standard 2.0., and apart from that i'm not getting any useful tool. If anyone knows any good tool, or by some means to compress and reduce the size of such files then it will be very helpful.
