PDF-XChangeViewer 5

When it came to the PDF reading, for long time, my favorite reader was Foxit Reader. It was much smaller, lighter, and faster than popular Adobe Acrobat. However, recently I found the free PDF viewer that gives even more options for the PDF files editing. Yes, it is true, with free viewer you cannot create PDF files, but with existing PDF files you can do almost anything. And when portable software appeared on the market, I decided to abandon my Foxit and to start using PDF-XChange Viewer. So far, I love the program. It is quick, smooth, and full of surprising features; with nice GUI and low amount of the utilized resources. May be, I will find some drawbacks with extensive use, but so far, I am happy with the program. Among its prominent features:

Tabbed Multiple Document Windows for viewing multiple documents at once.
You can add Comments and Annotations to any PDF file to provide visible feedback to the document creator.
You can mark-up pages with text and objects and type directly in Typewriter mode.
Ability to convert PDF files into images.
Extract text from the file through Copy and Paste commands.
Navigation enhancement for large or complex PDF files with Loupe and the Pan Window options.
Included plug-Ins for both MS IE and Firefox Browsers.
Additional features, such as Rotate and Crop pages.
Easy integration with translation software as ABBYY Lingvo 12, Translate It!, Lingoes.
And, finally, portable version: use it from any USB external drive or stick.
