    What contributes to the final size of a fixed layout ePub?


      I have two InDesign files, roughly the same size. The image links for file #1 come in at around 50MB total. The image links for file #2 come in at around 25MB total. Each file is roughly similar in terms of interactive content. Upon export with the same conversion settings, file #1 exports to about 18MB, and file #2 exports to around 30MB.


      I'm really at a loss as to why the second file is exporting a significantly larger ePub than the first, when the images it's linking are half the total size of the first file. Obviously I'm failing to consider something - what are other contributing factors to file size aside from the ones I've looked into?
