In this how-to tutorial, we will focus on the step-by-step process to convert Bitmap to PNG using Java by consuming a few simple API calls of the popular document conversion library. Further, we will develop a Java BMP to PNG converter application using the workflow defined in this article to demonstrate the image conversion from one format to another. Here are the key steps and a sample code for transforming a Bitmap file to PNG format.

Steps to Convert Bitmap to PNG using Java

1. Install GroupDocs.Conversion for Java from the Maven repository in Java application for implementing Bitmap to PNG functionality
2. Import essential classes for performing document transformation from a Bitmap to PNG format
3. Initialize the Converter class for loading the input Bitmap file for transforming to a PNG
4. Create an instance of the ImageConvertOptions class for setting the properties to customize the output PNG file
5. Finally, call the Convert method to save BMP as a PNG file on the disk

The above workflow is very easy to follow for creating the functionality to convert BMP to PNG in Java. You have to initialize the image conversion process by setting up the required library from the Maven repository and then import the essential classes in the code. Once you are done with the first two steps, then you have to load the input BMP file using the Converter class and define convert options for the output PNG file for customizing it using the ImageConvertOptions object. The last step helps you to perform the conversion and store the converted file on the disk.

Code to Convert Outlook Bitmap to PNG using Java

In the preceding snippet, we have developed the sample application to change BMP to PNG using Java with just a few lines of code and consuming a few API calls of the document conversion library. This code can be further extended by defining various properties for customizing the resultant file. Additionally, this sample code does not depend on any other software and can be used on any of the popular operating systems like Linux, Windows, and macOS.

We have discussed the detailed procedure to convert Bitmap to PNG in Java and created a sample application for it. Recently, we published an article on converting Image to Word in Java, take a look at how to convert Image to Word using Java post for more information.
