Evaluation versions of our SDK software are fully functional, allowing the testing and full utilization of all SDK features, Developers need to be aware that any test documents will have a demo watermark placed on every page of any PDF created or modified with the evaluation versions.
We recommend which ever option you decide is best suited for your needs - that you use the evaluation SDK's to the maximum prior to purchase to ensure satisfaction and only purchase when ready to recompile you completed application ready for distribution to your clients - with your license strings, to remove the demo watermarks restrictions
Please note: Developer SDK's cannot be refunded once licensing is issued!
The PDF-Tools SDK allows developers to build applications for the Creation, Manipulation, Viewing* and Printing* of PDF files. Please see the PDF-XChange/PDF-Tools SDK license included in the evaluation download for detailed information on terms and conditions and allowed usage, the core principle in regards allowed use age being that developers are free to us the products as they wish - provided the applications created are not competing with our own end user products and are not designed and incorporated in any application designed as a general purpose PDF creation, Manipulation or Viewing tool. If your application is designed for a vertical market, there is unlikely to be any conflict of interest. If in doubt - please do contact us for clarification.
* These options rely on the use of the PDF-XChange Viewer PRO SDK for which limited use is bundled with this SDK and for which distribution limits apply - if you need to distribute your viewer enabled applications to more than 2500 end user desktops, the purchase of extended Viewer PRO SDK licensing will be required.
