Try this function:

public static BufferedImage resize(BufferedImage image, int width, int height) {
    BufferedImage bi = new BufferedImage(width, height, BufferedImage.TRANSLUCENT);
    Graphics2D g2d = (Graphics2D) bi.createGraphics();
    g2d.addRenderingHints(new RenderingHints(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY));
    g2d.drawImage(image, 0, 0, width, height, null);
    g2d.dispose();
    return bi;
}

BufferedImage image1=ImageIO.read(url.openStream());
     BufferedImage resizedImage=resize(image,100,100);
     System.out.println("Load image into frame...");
      icon=new ImageIcon(resizedImage);
