I am a Chartered Accountant in public practice, and this is my go to PDF editor. I've used it for years now, and it turns out many of the public accounting firms are FINALLY moving away from the bloated and antiquated Adobe products. I've never had an issue with cross compatibility, and the mark up tools and options are exactly what I need.
It worked right out-of-the -box. The download was easy and I was impressed that it interfaces well with Windows 10. Thank you for writing an easy to use and essential piece of software!
I've enjoyed PDF Xchange for over 5 years now. I've used the viewer, standard, and pro editions. It's the best pdf software at the price. I have turned many companies on to it and they all love it.
I have to say, after struggling to find a good free PDF reader/editor, PDF XChange Editor is the best hands-down. You have included many "advanced" features for free - importing form fill fields, insertion of custom stamps, etc. that I find invaluable. At my institution, Adobe PDF forms are used heavily. At first, I was concerned about compatibility but I need not have worried. I have not encountered any problems. Furthermore, when I tried to export data from form fill fields or insert custom stamp using Adobe's free Acrobat Reader DC - I get sent to a webpage to "purchase" additional options/editions! You have a solid product, and now a devoted follower.
