![]() Note to calibre developers: Why did you not use standard image manipulation libraries? Why choose a heavy GUI-oriented framework (like Qt) for simple image operations? Quite a great package (calibre) with such a poor decision, in my opinion. ![]() ![]() Open the PDF you want to convert To begin, you first need to install Calibre on your computer if you havent already. Select the PDF file and open it in the application. The following is a quick guide to convert PDF to Epub using Calibre.

I also had to specify a command line option -mobi-keep-original-images, since I wanted to convert epub to mobi format using: ebook-convert ~/test.epub ~/test.mobi -mobi-keep-original-images Installing some missing python modules (which you figure out by running the convert command ebook-convert inputfile outputfile), in my case: python3-msgpack The steps involved extracting these directories from the calibre package (deb, rpm, whatever): /usr/bin/ebook-convert I've managed to cut out ebook-convert from Calibre (which, for who knows what reasons, requires Qt for image manipulation) and got a command-line only interface for it, to be able to use the tool on a headless/server machine.
