Tried a standard input tag with the proper accept attribute Selected a HEIC file from Photos in Safari, the selected image was automatically converted to JPEG. Ten bucks says College Board programmer(s) failed to do the most basic and standard filtering.

> Ten bucks says College Board programmer(s) failed to do the most basic and standard filtering. Why is it a failure of the college board to put "accept="image/jpeg"", instead of iOS which failed to default to the more standardized jpeg format when HEIC was not specified? HEIC is a newer format which fewer systems support. iOS / Safari should default to JPEG in this case.
2. Please try to read the entire comment. iOS does default to JPEG when uploading, the accept attribute isn't needed.
