still one of the worst converters, but highly praised. The results archived mostly differ that much compared to the originals, I always wonder what crap poeple nowadays. If a converter can't keep the textflow on mixed pages (single / multicolumn) which each second best worldprocesser is able to, the best thing to do is to better not mention it, since poeple get disappointed reading books forward beackward each 3 or 4 pages. And Calibre is one of the poorest ones if it comes to this discipline ... still.

Hi, Nagraj

Does calibre show anything like "DRM protected" or other info?

If that PDB is purchased from eReader, it is likely to be DRM protected, which will have to be DRM stripped before the conversion.

Refer to this post for more details:

Hello I converted files from pdf to mobi but they look weird on my kindle, the line ends in the middle of the screen, the spacing is alright two lines in a row and then there's a huge space beneath them. It's very uncomfortable to read this way, is there any optimal setting which I could use that would make the text appear as if on a page in a regular book?

Calibre is an amazing piece of software, it is a powerful conversion tool that allows you complete control over the output of your book. That being said, I understand that some people may have trouble getting started with all the options in the conversion process. I suggest you check out the wealth of "How to's" and "Tips and Tricks" online. Calibre's site has a downloadable manual along with online step by step instructions, another site to check out is the MobileRead Forums. I was overwhelmed myself at first, however, I can assure you that if you put some time into learning the program you will come to appreciate how much it really kicks Arse! Btw, pdf's are really difficult to convert correctly because the are basically an image file.
