How to Convert Byte[] to BufferedImage in Java

Through this tutorial, we will learn how to convert byte[] to BufferedImage in Java.

Source Code

package com.beginner.examples;

import java.awt.image.BufferedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;

import javax.imageio.ImageIO;

public class ConvertByteToBufferedImage {

	public static void main(String[] args) {
		try {
			BufferedImage image = ImageIO.read(new File("E:tmptest.jpg"));
			ByteArrayOutputStream baos = new ByteArrayOutputStream();
			ImageIO.write(image, "jpg", baos);
			baos.flush();
			byte [] imageByte = baos.toByteArray();
			baos.close();
			
			InputStream in = new ByteArrayInputStream(imageByte);
			BufferedImage bImageFromConvert = ImageIO.read(in);
			ImageIO.write(bImageFromConvert, "jpg", new File("E:tmptest.jpg"));
		}catch(IOException e) {
			e.printStackTrace();
		}
	}
