Reply To: Transparent png gets white background in epub

Off the top of my head, I’m guessing it’s simply an easy way to keep the file size small. Now I’m wondering how it decides what PNGs to convert and which it doesn’t, I have some that export certain PNGs fine (not sure if the ones I’m thinking of have transparency though), so I’m wondering if there is a file size limit or something on export that determines which stay PNG and which are converted to JPG.
