PNG would be unnecessary. The original file format from the Ebook was .JPG. Converting to PNG would only make the filesize larger, and wouldn't improve the quality at all. I'm surprised you don't know this.

While you can "adjust the scale" of your zoomed in lower quality image and the differences aren't noticeable to you, there's a difference that I can clearly see. I could argue that if you want to see it bigger, you could just zoom in. Or you could create superior quality zoomed-in images by just throwing it through waifu-2x, though I prefer to go with the original source.

I know what I'm talking about here.
