I have multiple PDF of my lecture notes and was hoping to convert these to ePub format where the name of the PDF forms an entry on the contents page. I want to do this because I think ePub will be a smaller format and if I can get it below 50mb I can upload it to Google Play Books. It is essentially a lot of presentations in PDF format, where I presume the pictures accounts for the large collective size.
I am not sure if this is the right section, please forward me to the right section if this isn't it. Thanks!
