title: how to save simple image in pillow-python without any change in quality?
body: <p>I'd like to store an image with the exact copy as the original without any change in quality,</p>
  
  <p>When i set <code>quality=100</code> in Pillow Python, The saved image has <strong>5kB less</strong> space than the originial</p>
  
  <p>How do i retain the size? I'm retreiving the image from streams</p>
  
  <pre><code>from PIL import Image, ImageFilter
  
  image = Image.open("image.jpg")
  file_path = io.BytesIO();
  image.save(file_path,'JPEG',quality=100);
  file_path.seek(0);
  
  image2 = Image.open(file_path)
  
  
  image2.save("image_copy2.jpg",'JPEG');
