        <julian45[m]> "i don't think so, i _know_ i'..." <- i know i have too. other formats too. i just assume they transcode as iirc they always _return_ jpeg. e.g. if you see the [CAA API page](https://beta.musicbrainz.org/doc/Cover_Art_…, all the images and thumbnails are `jpg`.

        and judging by [this line](https://github.com/metabrainz/libcoverart/b… from libcoverart, i assume that jpegs are always returned. i am unable to find the source for the IA's side though. not sure it's even source available?

        They definitely don't transcode the original PNGs, and especially not PDFs!

        But if you are grabbing the resized images (e.g. 1200x1200px) I believe it will always be jpg

        (in case you missed it the formats seem to be, according to the wiki - gif, jpg, jpeg, png, htm, html, jpe, jfif and pdf (https://musicbrainz.org/doc/How_to_Add_Cover_Art) )
