Method

Stringencode(RenderedImage image, String formatName)
encode 
try (ByteArrayOutputStream baos = new ByteArrayOutputStream();
        BufferedOutputStream bos = new BufferedOutputStream(baos);) {
    ImageIO.write(image, formatName, bos);
    bos.flush();
    return Base64.getEncoder().encodeToString(baos.toByteArray());
} catch (IOException e) {
    throw new RuntimeException(e);
voidencodeAndWriteJPEGFile(File file, BufferedImage image, float quality)
encode And Write JPEG File 
Iterator<ImageWriter> iter = ImageIO.getImageWritersByFormatName("jpeg");
ImageWriter writer = iter.next();
ImageWriteParam iwp = writer.getDefaultWriteParam();
iwp.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);
iwp.setCompressionQuality(quality);
FileImageOutputStream output = new FileImageOutputStream(file);
writer.setOutput(output);
IIOImage iioi = new IIOImage(image, null, null);
...
byte[]encodeBufferedImageAsJPEG(BufferedImage bi)
Stores BufferedImage as JPEG encoded bytestream 
byte[] byteStream = null;
ByteArrayOutputStream baos = new ByteArrayOutputStream(1024);
ImageIO.write(bi, "jpeg", baos);
baos.flush();
byteStream = baos.toByteArray();
baos.close();
return byteStream;
StringencodeImage(BufferedImage image)
encode Image 
String imageString = null;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try {
    ImageIO.write(image, "png", bos);
    byte[] imageBytes = bos.toByteArray();
    imageString = DatatypeConverter.printBase64Binary(imageBytes);
