PowerPoint Library for C# and VB.NET applications

GemBox.Presentation is a C# / VB.NET library that provides a simple and efficient way to process PowerPoint files. It enables developers to read, write, convert, and print presentation files (PPTX, PPT, PDF, XPS, and image formats) from .NET applications without a need for Microsoft PowerPoint on either the developer or client machines.

GemBox.Presentation requires .NET Framework version 3.5 or above.

GemBox.Presentation Examples are listed on the right side of the page. Use the list to explore the supported features.

Below the example description there are Run options used to specify the output file format and execute the example using GemBox.Presentation in Professional mode (without any limitation). For more information about GemBox.Presentation modes (Free, Trial, Time Limited, and Professional), see Evaluation and Licensing help page.
