When it comes to pdf readers Windows users have lots of choices. From Adobe Reader over third party alternatives such as Sumatra or Foxit Reader to built-in pdf readers in browsers such as Google Chrome. When it comes to creating pdf documents, the choice shrinks significantly.

Nitro PDF Reader has received lots of praise in the past for its pdf viewing and creating capabilities. The developers today have released version 2 final of the program. A lot has changed compared to the previous version. Among the new features are browser plugins for Mozilla Firefox, Google Chrome and Internet Explorer, a new thumbnail handler for Windows Explorer (32-bit) to generate better pdf previews and support for layers and rendering transparency in pdf fles.

The Nitro Reader features include abilities to fill out and save PDF forms, stamp a signature on a PDF, extract text and images, comment, highlight or strikeout text, and more. New enhancements to 2.0 include:

· QuickSign – import a scanned image of your handwritten signature to sign documents electronically in just seconds

· Microsoft Office Interface – Unlike other PDF Readers, the Nitro PDF Reader uses the same interface as Microsoft Office products, so users know exactly where to find things

· It’s faster – files open instantly, PDFs are created 4x times faster

· It’s lighter – using much less RAM in its runtime, even with multiple PDFs open

· Files are lighter – now the PDFs you send are half the size

· Browser integration – you can open and save PDF in popular browsers like IE 9.0 and Firefox 4.0 without having to switch back and forth between software programs

According to its developers, Nitro PDF Software is now creating pdf documents up to four times faster than its predecessor. It also lighter on computer memory and creates pdf documents that are lighter in size. A short test opening some pdf documents showed that Nitro PDF Reader 2 is about as fast as the lightweight pdf reader Sumatra when it comes to opening pdf documents. Keep in mind that the program offers additional functionality for viewing and creating pdf documents, that Sumatra does not offer.

    I have installed this Nitro PDF version 2.o.o reader and i have to say that i am impressed this because its a smooth operator, with a minimum off bloatware.
    This is certainly nicer than Adobe and the new Firefox, with nice functions like minimize the ribbon and filling up your screen with the hole PDF document.
    This latest version is a improvement of what outer PDF readers are offering.
    For a free version it offers a lot a functions an am going to look what the pro version is offering for extra’s. Nice find Martin.

    Hoi Martin, Are you still cleansing on to the Adobe reader, and not using him, or is this PDF reader your new PDF reader. Or did you make another choice already?
    Main second question is because I cant find out or this reader is compatible with Firfox 5.0, do you know anything more about that?

      The plugin installed fine on my Firefox 6 Aurora installation. Did not test if it worked though, but it is enabled. I still have Adobe Reader X installed, but as I said before, I do not really need a pdf reader that much.

    After using several freeware PDF readers, I ended up using Sumatra. It’s light and fast loading, and just works. PDF-Xchange and Foxit suffer from feature-creep, when all I really wanted is just something that opens PDF files fast.

    I’ll give Nitro a shot but I doubt that it can replace Sumatra for me. For instance, the ribbon takes too much screen real estate.
