I used Calibre. It seem to work for most of my conversion from PDF to ebook.

Sometimes, when I do not want to deal with converting and then editing a book. I use a crop program like BRISS. It helps reading on my device. Also allows me to sort of get what I want.

i have a couple of programs for converting from epub to mobi and pdf to mobi..however they didnt always seem to work..but i found this site.... http://www.convertfiles.com/convert/ebo ... -MOBI.html
which is fantastic...you can convert virtually any file to whatever you want.

I have tried kvisoft flip book maker. They have similar functions. People can convert PDF to flip ebook easily.

The best and most powerful tool by far is Abbyy Finereader.

Of course it also requires the most work

Just treat it like a scan and do an OCR on it, works like a charm

You can try pdf flip book software. It allows people convert pdf to flip ebook easily.

The latest Calibre is much quicker to convert PDF to ebooks now
