How-to: Convert JPG to PDF using ImageMagick

It's a common enough task, trying to convert multiple jpg files into one pdf, particularly when I don't need these to be converted with such high quality, I just want the black and white text readable. I can scan, crop, and monochrome in a graphics program but compiling them into a single PDF booklet was always tricky. Which is how I started using ImageMagick . ImageMagick is a command line conversion program that is capable of so many more batch operations than this - resizing, compression, format conversion - and it's available on all platforms - Linux, Windows and Mac.
