Answer Line: How to Convert CHM to PDF on Mac

Okay, so I’ve got Dropbox with a whole bunch of tech books in CHM format. I am familiar with Calibre. It is a great product with a lot of great features.

When using an iPad Mini and running Calibre on a MacBook Pro. All my CHM ducuments has a lot of images and I noticed that some of the images are being cut off...well let me explain further...a lot of images are being split up between two pages...part of the image will be on one page and when you get to the next page the rest of the image is there. So is there any other ways to view all my CHM files properly on Mac, iPad or iPhone?

In business you may sometimes receive documents saved in CHM format, which is a format of help files developed by Microsoft for publishing help manuals with their software and application releases.
