Nitro PDF Reader allows you to make notes and edit PDFs as well as simply read them, offering a huge advantage over other free PDF software options.
Quick start guide: When you launch this program for the first time, it opens a quick start guide that runs you through the basic operations.
Sign and mark up documents: Nitro allows you to add notes and mark up a document, as well as to easily sign a form with your electronic signature.
Easy PDF creation: If you need to create a PDF, you can just drag and drop files into Nitro. It recognizes more than 300 other file types and allows you to create PDFs from them.
Long installation: The installer gave us quite a bit of difficulty during testing. We had to cancel it once, and the second time we ran it, it took an exceptionally long time before completion.
If the regular free PDF software isn't giving you enough functionality, then Nitro PDF Reader might fill the gap.
