title: SixLabors ImageSharp produces huge image files
body: <p>I use the below code to resize JPG files to 200x240 pixels. The attached example file has a size of 900x600 pixels and is only 84 kb. However when I save the resized file using ImageSharp, the produced image is 435 kb! Why is the smaller image has a bigger file size?</p>
  <p>I noticed that the bit depth of the original image is 24 bits but ImageSharp stores it with 32 bits. How can I reduce this?</p>

  <pre><code>var thumbImage = image.Clone(x =&gt; x.GetCurrentSize());
  
                          if (thumbImage.Width &gt; 200)
                          {
                              thumbImage.Mutate(m =&gt;
                              {
                                  m.Resize(new ResizeOptions
                                  {
                                      Mode = ResizeMode.Min,
                                      Size = new Size(200, 0)
                                  });
                              });
