This is not about another Acrobat Reader alternative, it’s an excellent alternative to the $299.00 Adobe Acrobat PDF editor. For the past couple months I’ve been using the free PDF-XChange Viewer from Tracker Software Products for all my PDF editing needs. I found the UI to be as easy to learn and use as my favorite office suite, OpenOffice. The free version has all of the features many users will ever need in a PDF editor. For only $29.50 the Viewer PRO edition adds the rest of the features that are in Adobe’s product. My employer provides me with the full Acrobat product on my workstations but I’ve liked PDF-XChange Viewer so much that I bought the Pro version myself and am using it exclusively now.
Keep in mind this program is not for creating PDF’s it’s for editing existing PDF’s. For creating PDF’s I exclusively use and highly recommend the free open source PDF Creator from PDF forge.
