I was not able to find any list of what file formats are acceptable to upload for the creation of a deck of flashcards. Obviously .jpg works for pictures, but what about .png for example? Same for audio files. I trust .mp3 is acceptable, but what other file formats will work? When I download something for a set of flashcards, I would like to know if I need to convert the file format before finding out I saved/used an incompatible format.
Thanks
