FAQ

About this plugin

Questions about trials, licenses and payment are answered once, on Pricing & licensing.

Can I try Merge PDF before buying?
Yes. Install the package and run the plugin in evaluation mode; it adds evaluation messages and a three-page limit applies until a license is set. For a full test, request a free temporary license.
Is there an online demo?
Try the PDF Merger App, powered by the same merger engine.
Does the plugin work with other document formats?
Each plugin works with one format: JoinPdf accepts PDF 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.
