Both are command line utilities.
Ffmpeg powers virtually every audio / video web or desktop player that's ever existed, from youtube, netflix to vlc.
Pandoc is the ultimate converter tool to convert from and to html, docx, pptx, md, etc.
For pdf specifically, you can combine pandoc with poppler tools to convert a pdf to anything else. Pandoc can't convert from pdf, only to pdf.
Even if you have no experience with command lines utilities, I believe that for most of your use case asking chatgpt or any other llm how to convert x file format to y with x tool will give you a command you could just copy paste and 99% of the time it will work. The only thing you'd really need to understand is how to navigate between folders with cd.
With those 3 you probably won't need anything else as virtually all the converters online or offline use those under the hood to do the actual conversion.
Let me know if you need more details / help!
