Contents Summary

You can use GroupDocs.Merger without the license. The usage and functionalities are pretty much same as the licensed one but you will face few limitations while using the non-licensed API.

Evaluation Limits

  1. Result document will be trimmed to 3 first pages
  2. GroupDocs trial badges are placed in the document on the top of each page


The license file contains details such as the product name, number of developers it is licensed to, subscription expiry date and so on. It contains digital signature, so don't modify the file. Even inadvertent addition of an extra line break into the file will invalidate it. You need to set a license before utilizing GroupDocs.Merger API if you want to avoid its evaluation limitations.

Applying Metered License

You can also set Metered license as an alternative to license file. It is a new licensing mechanism that will be used along with existing licensing method. It is useful for the customers who want to be billed based on the usage of the API features. For more details, please refer to Metered Licensing FAQ section.
