License Just What You Need

The PDF SDK is licensed per project or app on an annual subscription basis. Priority Support, updates, upgrades, new versions, and replacement software are included.

The license covers the right for your developers to use the SDK for one end-user application. Each SDK comes standard with one input format, one output format, and 50 deployment licenses, all of which can be extended. The PDF SDK may not be used to make a developer toolkit or product that contains an API.

Deployment Licenses grant you the right to integrate and distribute our libraries in your resulting application. One deployment license is required for every user of your app. If you want to deploy it on devices or appliances, please contact us.
