Merging multiple images into a single file is perfect for building galleries, consolidating product photos, or stitching scanned documents together. This capability streamlines your workflow, saves valuable time, and delivers a clean, organized output—essential for apps and websites that demand a smooth, seamless user experience. In this tutorial, we’ll show you how to quickly merge multiple JPG files using the Cloud .NET SDK.

Steps to Merge Multiple JPG Images using .NET REST API

1. Sign up and get your API credentials from the GroupDocs Cloud Dashboard
2. Install GroupDocs.Merger Cloud .NET SDK using the NuGet package
3. Use the Configuration class to configure your API credentials
4. Instantiate an object of the DocumentApi class
5. Set up the source JPG images to merge, and set the orientation
