If you’re here, you are probably trying to find the best Web publishing service. Both 3D Issue and Issuu are big names in Web publishing. They offer a slick set of features for anyone looking to publish PDFs online with good presentations and some extra tools for editing and spreading the content. But before you commit to a big, expensive subscription to one of these services, I suggest you look harder at a third service. It’s called Yumpu Publishing, and it has all of the features that either 3D Issue or Issuu offer as paid features for free.
