PDF is not well supported in portable devices like iPad iPhone Mobile Phone PDA. Thus we should tranform pdf file to epub format which is a free and standard ebook format and supported by most of mobile devices. Though some devices begin to support pdf format such as iPhone iPod Touch with iOS 4.0 the iBooks app is upgraded 1.1 this version of iBooks in iPod Touch and iPhone supports PDF format now but considering the small screen of iPhone and iPod Touch it is not very convenient to read PDF eBooks on the devices because you have to drag the scroll bar from left to right each time to read a line of text in a single page from one PDF eBook. So here comes the EPUB. EPUB is designed for reflowable content meaning that the text display can be optimized for the particular display device. That means EPUB eBooks can adjust the screen size of your devices automatically so you don''t need to drag for reading your eBooks anymore! If you already have some PDF eBooks on your computer converting PDF to EPUB on Mac or converting PDF to EPUB on PC and then transfer the converted PDF eBooks to your iPhone or iPod Touch for reading will be a good choice!
