you use "ls" to list folders inside current directory, and "cd foldername" to go in that folder. "cd .." returns you one folder back
there is also tab button above the keyboard, it autocompletes with filenames and directories so you dont have to manually type everything see pic related its circled in red
>after you're in the folder with the image you type>ffmpeg -i imageyouwannaconvert.png nameofconvertedimage.jpgffmpeg is the program -i is the input followed by the filename and last is the filename and format of what you wanna format.
if you need a gui for that then i feel sorry for you
