I've given pdflrf windows version a try and it works well. Probably the easiest out of all the ones I have managed to find. Hasn't had any files needing renaming. Though it doesn't look like it can batch convert, if you just select the files then drag and drop it'll convert it for you no problem.
Only things that is putting me off it as my sole converter is that I can't get it to a large landscape (double page) image into two single page images. Maybe the options are there, but it's not all that clear. And it doesn't seem to retain previous settings - so i'll need to keep it active or change the settings everytime I set it up.
It doesn't half have a misleading name though, thought it could only handle pdfs.
