Common Questions and Concerns

Quick answers to frequently asked questions about licensing, trials, downloads, and more.

Can I evaluate GroupDocs plugins before buying?
Yes! You can download and try any plugin. Evaluation mode includes limitations such as watermarks or restricted processing.
For full-feature testing, you can request a free temporary license before purchasing.
Do you offer product demos?
While we don’t offer live demos, you can explore how our products work through the GroupDocs Apps website, which is powered by our High-Code libraries.
Where can I download the package?
All packages can be downloaded from NuGet.
How does licensing work for developers?
Our licenses are issued per developer—not per user or machine. This allows flexibility if your team changes over time.
What does the $99 license include?
The $99 license provides a perpetual developer license for a single plugin within one of our package.
There are no subscriptions or hidden fees. For example, you can purchase a license for the DOCX to PDF converter plugin, which is part of the GroupDocs.Conversion.LowCode package.
