We will discuss the image transformation from one format to another using one of the popular document conversion libraries and provides the stepwise process of how to convert Bitmap to PNG using C#. We will also create a sample application for C# BMP to PNG converter using the workflow described in this article. Here are the key steps along with a sample code snippet for converting Bitmap to PNG format.

Steps to Convert Bitmap to PNG using C#

1. Install GroupDocs.Conversion for .NET package from the NuGet package manager in the .NET application to convert Bitmap to PNG
2. Add a reference to the GroupDocs.Conversion namespace for developing the Bitmap to PNG conversion
3. Create an instance of the Converter class for loading the input Bitmap file from the disk for transforming to PNG format
4. Create and define convert options for the PNG file to customize it
5. Call the Convert method of the Converter class to save BMP as PNG on the disk

You can quickly and easily change BMP to PNG in C# by following the above workflow and writing a few lines of code that contain API calls of the document conversion library. You can also set a variety of convert options for the output PNG file for customizing it using the ImageConvertOptions object. These instructions do not rely on any other software and can be used on common operating systems like Windows, macOS, and Linux.

Code to Convert Bitmap to PNG using C#

We have developed the application to convert BMP to PNG in C# with the help of the workflow explained in the previous section for demonstration. As you can see in the above code snippet, we have used the Converter class for loading the input Bitmap file using its constructor after setting up the required package from the NuGet website and including the necessary namespaces. After that, we have created an object of the ImageConvertOptions class for customizing the resultant file and then called the Convert method for doing the image conversion and storing it on the disk.

We have discussed the document conversion process to convert Bitmap to PNG in C# and developed an example for it. Recently, we published an article to change Image to Word in C#, have a look at how to convert Image to Word using C# guide for more information.
