I used to use FoxIt. I used to like FoxIt. But I dont like the fact that basic tools are not free and are insted part of the PRO pack (eg – annotations).
And in my quest for a free PDF viewer that supports annotations – I found PDF-XChange Viewer. In my opinion PDF viewer is just as fast as FoxIt and it supports a variety of annotations and markup for free.
Here is an example of some annotations that I made to a PDF file:
You can save the PDF file with all your annotations, and PDF Xchange Viewer will not save the document with any annoying watermarks, etc. The one thing to remember is that there are some PRO features if invoked will lead to the file being saved with a water mark. (A good work-around is to hide the pro features via the preferences—>Registration options window – shown below).
One final note – another great feature of PDF XChange viewer is that it remembers the last page you were viewing even after you close and reopen the file. This makes it a great app to read your ebooks.
My only wish – it had an easier single word name. PDF XChange Viewer doesnt roll of your tongue as Foxit or Acrobat.
