All of our desktop products are based on the same engine that drives our developer tools. Because of this, we recommend a two-step approach to evaluations. First, get a reliable indication of the core functionality and output quality by performing test conversions simply using end-user 30-day trial versions. Then, using additional documentation, the same standard Windows download will also allow testing of the command line, which is a straight-forward interface for many development environments. Contact us for instructions on how to use it if the information provided on the web-site is not sufficient. Evaluations of the API/DLL are available for download also. Please contact email@example.com for the download link.
