I just launched PDFtoEPUBAI.com, a simple website that lets you convert any pdf into an epub while retaining formatting, images, tables, and simpel equations. (Complex equations are being worked on but EPUB is an annoying format, so we will see.)

I used to print out a lot of papers because I hate reading on a regular screen for long periods of time, and there was no reliable and clean way to read them on my Kindle. Now I can simply convert them and send them to my Kindle. Maybe some of you have the same problem. Try it out for free!
