An evaluation or commercial license key is required to run PDFTron. If you are evaluating the SDK and do not have a key, please obtain one, and then visit this page via the link included in the trial email. If your company has licensed PDFTron then you already received your key in an email from See sign in for more details.


If you are evaluating PDFTron products, and you get an error stating that you need a valid key, then you need to request a demo license key. Once you have the demo key you add it to your PDFNet.Initialize call.

For more details please see the corresponding documentation for your platform.

If you have purchased a license key from PDFTron, then you would pass it into your call to PDFNet.Initialize or into your WebViewer constructor's l parameter. You should have received more detail instructions in the email that sent you the purchased license key.

Multiple production keys
While you are evaluating our products a single demo key can be used everywhere, however when you purchase a license, you may receive multiple license keys, for use on different platforms.
