In this how-to tutorial, we will concentrate on the stepwise instructions to convert PNG to JPG using Java and how to use this guide for implementing the Java convert PNG to JPG functionality. This guide can be followed on any common operating system including Linux, macOS, and Windows without setting any additional software. Here are the main steps along with the sample code snippet to convert PNG to JPG in Java.

Steps to Convert PNG to JPG using Java

1. Install GroupDocs.Conversion for Java from the Maven repository in Java project for implementing PNG to JPG capability
2. Import essential classes for performing document conversion from PNG to JPG format
3. Instantiate the Converter class for loading the input PNG file for transforming to a JPG file
4. Create an instance of the ImageConvertOptions class for defining the parameters to customize the output JPG document
5. Finally, call the Convert method to save the PNG as a JPG file on the disk

We have outlined the key steps that are essential for developing the Java PNG to JPG functionality. This workflow is simple to follow for doing conversion between image formats using a few API calls of the document conversion library. Moreover, you do not have to set up any additional software to use these instructions and can be used on any of the common operating systems including Windows, Linux, and macOS.

Code to Convert PNG to JPG using Java

In the preceding snippet, we have created the PNG to JPG Java code to demonstrate the implementation of this feature. You can see in the sample code that it is a matter of writing a few lines of code to transform an image into the required format after setting up the document conversion library and importing the necessary classes.

We have discussed the detailed procedure for developing the PNG to JPG converter in Java and created a sample code for it. Recently, we published an article on converting XLSB to PDF using Java, take a look at how to convert XLSB to PDF in Java post for more information.
