If I had to do this? Not Gimp, use ImageMagick. see
https://www.imagemagick.org/script/download.php

Can be a simple as.

magick mogrify -format jpg  *.png

will convert a folder full of png images to jpegs.

On the other hand, if you want to see each image before exporting, the attached
rough-n-ready script exports to a 90 quality jpeg. You need to specify the
destination but only once per session. Unzip, pop in your plugins folder (it is
python) check that it is executable.
