ComPDFKit PDF SDK is a commercial SDK, which requires a license to grant developer permission to release their apps. Each license is only valid for one ApplicationId in development mode. ComPDFKit supports flexible licensing options, please contact our marketing team to know more. However, any documents, sample code, or source code distribution from the released package of ComPDFKit to any third party is prohibited.

Online License: We have introduced an online license mechanism for enhanced license management. Through the online approach, you can manage and update your license more flexibly to meet the specific requirements of your project.

Offline License: In scenarios with high security requirements, no internet connectivity, or offline environments, we provide the option of an offline license. The offline license allows authorization and usage of the ComPDFKit PDF SDK when internet connectivity is not available.
