图片格式转换webp

今天突然保存梅西夺冠照片，发现google上下载的图片是webp格式，好新颖的格式。

百度了下，webp是google推出的必jpg格式更小的图片格式文件，但是softpage等浏览器还不支持，WIN11设置背景图片也不支持。

既然不支持，那就只有转了。网上下载的工具不付费有水印，就只能自己撸代码干了。

 

添加jar包，写个简单工具类

package org.example;

import com.luciad.imageio.webp.WebPReadParam;

import javax.imageio.ImageIO;
import javax.imageio.ImageReader;
import javax.imageio.stream.FileImageInputStream;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

public class WebpUtils {

    public static void main(String[] args) throws IOException {
        String basePath = "C:\\Users\\22952\\Pictures\\Saved Pictures\\";
        String webpPath=basePath+"goat.webp";
        String pngPath=basePath+"goat.png";
        //webpToJpg(webpPath,pngPath);
        System.out.println("done");

        String webpPath1=basePath+"goat2.webp";
        jpgToWebp(pngPath,webpPath1);
    }

    public static void webpToJpg(String webpPath,String pngPath) throws IOException {

        ImageReader reader = ImageIO.getImageReadersByMIMEType("image/webp").next();

        WebPReadParam readParam = new WebPReadParam();
        readParam.setBypassFiltering(true);

        reader.setInput(new FileImageInputStream(new File(webpPath)));
        BufferedImage image = reader.read(0,readParam);

        // png can be replaced by jpg
        ImageIO.write(image,"png",new File(pngPath));


    }

    public static void jpgToWebp(String pngPath,String webpPath) throws IOException {

        BufferedImage image = ImageIO.read(new File(pngPath));

        ImageIO.write(image,"webp",new File(webpPath));


    }
}
