How to convert WEBP into PNG in Java

1. Read WEBP image into Java

   BufferedImage bufferedImage = JDeli.read(new File("webpImageFile.webp"));  
   

2. Process image if needed (scale, sharpen, lighten, watermark, etc)

   bufferedImage = operations.apply(BufferedImage bufferedImage); // Optional
   

3. Write out BufferedImage as PNG image file

   JDeli.write(bufferedImage, "png", new File("pngImageFile.png"));

Export WEBP to PNG in one line of code

The JDeli.convert() methods allow you to save WEBP as PNG in just ONE line of code!

Using File

JDeli.convert(File inFile, File outFile);

Using InputStream and OutputStream

JDeli.convert(InputStream inputStream, OutputStream outputStream, "png");

Using byte[]

byte[] outputData = JDeli.convert(byte[] inputData, "png");

Configure Output Settings

This option allows you to specify an EncoderOptions object to configure output settings such as image compression.

JDeli.convert(File inFile, EncoderOptions outputOptions, File outfile);

Batch convert WEBP to PNG from command line

Change image formats from command line or bash, bat, and powershell scripts. This method can also be used to invoke JDeli from any programming language that allows you to create a child process.

java -jar jdeli.jar --convert png "inputFileOrDir" "outputDir"
