It works well and fulfilled all my needs for many years., but when I needed to transfer the licence from one laptop to another things fell apart.

I really enjoy the comprehensive features that assist with work efficiency and integration with Microsoft programs.

The text editing and conversion tools to Microsoft Office formats are simply magical.

I have tried several PDF tools, both free and paid versions and I have chosen NitroPDF as my go to application.

Incorrect information from support, quick to take money for a licence impossible to get it back when they fail to provide the software.

I love the digital signature and document modification features the most.

Lacks the advanced features of Adobe Acrobat Pro.

It is not always a 100% match for what Adobe can do depending on what features you need, so there are some times when we need to reach outside of the product to find a solution.

The optimization feature could be better.
