Viewing PDF documents this way is one of the main features of the program, you can also read them see a more traditional way, by turning pages with the keyboard and stored them in a duplex, or full screen.
The program also allows us to create PDF documents from Word, Excel or Powerpoint. All you have to do is
is upload and click, but yes, you must first register in the website.
Very interesting is also the ability to read digital comics CBR and CBZ format which you may read in the traditional format.
Soda 3D PDF Reader is a great PDF viewer that has a 3D option and a good amount of features that any user can use without a hassle.
