converting .webp to .jpeg using Java

Question

i want to convert a .webp image to .jpeg. I have used javax.imageio.ImageIO.

but @ line no: 19 bImage = ImageIO.read(fis); returns a null for webp images.

Code is working fine if I try to convert .png ,.gif file format..

can any one help?

public static void imageIoWrite() {
    BufferedImage bImage = null;
    try {
        File initialImage = new File("resources/1.webp");
        FileInputStream fis = new FileInputStream(initialImage);
        bImage = ImageIO.read(fis); //why it returns null?
        if (bImage != null) {
            ImageIO.write(bImage, "jpg",
                    new File("resources/NewImage1.jpg"));
            System.out.println("Image file written successfully");
        } else {
            System.out.println("imag is empty");
        }
    } catch (IOException e) {
        System.out.println("Exception occured :" + e.getMessage());
    }
}

It seems that ImageIO is not able to read webp images. As you can read in the docs, the method read returns null in this case. I think that you have to use an additional library to read and write webp images.
