Despite numerous product available in the internet which is able to generate PDF (Portable Document File), Adobe Acrobat Pro series never short of idea to make it stay the way it use to be. Below is the screen shot of the latest incarnation Adobe Acrobat 8 Pro welcome screen.

The welcome screen alone make me feel “Wow”. I never thought all these features will be wrapped in one neat package.
I bet someone of you might ask, why we should use PDF. Why PDF exist?
Basically, we have countless productivity suite or software to date. Ranging from Office suite to Technical Software like CAD/CAM or Circuit Simulator, it is impossible to ensure our audience (the person who are going to get our file/work) have same software like yours. By convert it to PDF, and attach the reader with it (not necessary Adobe Reader as FoxIt will be a lot smaller XD), you can rest assure that your audience able to read and view that file the way you want him/her to be.
Another factor is security. You can set various kind of security mechanism to protect your intellectual property. You may allow them to read the documents but can’t save and print.
So back to the topic, why should we invest for Adobe Acrobat 8 Pro? Isn’t CutePDF or PrimoPDF free version not enough? Answer : Depend.
It depend on your need and working environment. Those free software basically only allow you to convert file to PDF by applying virtual printer method. So, you may forget table of content, link etc. Below are Acrobat 8 Pro strong features worth to be considered.
