I want to convert PDF files on server-side, should I purchase PDF Server or PDF Driver?

Please consider the followings:

1. Interaction: Gaaiho PDF Server has two flexible interaction methods, personal interaction and automatic server interaction. Gaaiho PDF Driver only supports conversion by manually operating.
2. Remote/Virtual Use: Do you want to install software on each computer, or your customer has remote system, virtual desktop or virtual application system? In this case, we suggest you to choose Gaaiho PDF Driver Terminal Server License or deploy the watch folder of Gaaiho PDF Server.
3. How much is the budget? Gaaiho PDF Server is more costly. If you have low demand for PDF conversion, it is suggested that you purchase Gaaiho PDF Driver license for each user.
4. Do you need develop program? Some functions are not implemented in application, but developers can call functions through writing program based on Gaaiho PDF Server. For details, please refer to our SDK information.
