Common Questions and Concerns

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

  • Can I evaluate GroupDocs products before buying?
    Yes! You can download and try any merger plugin in evaluation mode—trial limitations apply (e.g., evaluation messages and a three-page limit). For full‑feature testing without restrictions, request a free temporary license before purchasing.
  • Do you offer PPTX merging demos?
    We don’t provide live demos, but you can explore our functionality via the PPTX Merger App, powered by our document merger SDK.
  • Where can I download the package with merger plugins?
    You can download or install the GroupDocs.Merger.LowCode package via NuGet.
  • How does licensing work for developers?
    Licenses are issued per developer, not per user or machine, so your team can change without requiring license updates.
  • What does the $99 license include?
    A one‑time $99 purchase grants a perpetual developer license for a single plugin of our Document Merger Plugins, such as Merge PPTX. Each plugin is licensed separately. There are no subscriptions or hidden fees.
  • Does the plugin work with other document formats?
    Each plugin works with one format: JoinPptx accepts PPTX documents only. To merge, split, or remove pages in other formats, or to combine documents of different formats, use the full GroupDocs.Merger for .NET SDK.
