Let me tell you a little bit about all those various file converter tools, be it ffmpeg, pandoc, imagemagick, whatever.

The majority of them can be used like this: magick inputfile.bmp outputfile.jpg. If all you need is this file in that format, that’s how you do it. They’re ridicluously capable, you can do editing and compositing and such with them and whatever. If you have a use case where you do that a lot, like you just always put a watermark on images or you always desaturate them or whatever, you can write a script, then just run that script.

They’re basically all like that. Fairly simple to use for basic format translation, shockingly capable if you want to write a script.
