I found out that I can do it easily on the iPhone, but definitely not the desktop program running on my Mac.
One problem I am seeing common to many conversions from HEIC images to JPG is that they are over sharp. It was especially prominent today when I shot a photo with my phone today and then edited it directly in Ribbet. I am seeing this problem in a number of apps and also in online converters. Thanks for answering right away.
