Convert JPEG To PNG With ffmpeg

The ffmpeg utility "is a universal media converter." That means we can use it to convert, for instance, a JPEG file to a PNG file.

There is not a lot to a conversion like this. We use -i to specify the existing input file (a JPEG) and then the other argument is the name and extension of the output file.

$ ls
profile.jpg

$ ffmpeg -i profile.jpg profile.png

$ ls
profile.jpg  profile.png

See man ffmpeg for more details.
