| If we invoke the web-optimization capabilities of Photoshop, it looks a lot better. With the aid of web-optimization, Photoshop can reduce the JPEG size to about 7.1 kb before it starts to lose quality (left photo below). A 6.6 kb GIMP image is shown on the right. A 10.3 kb GIMP image is shown in the middle as a quality comparison standard. If you prefer to use a 57.6 kb image as a quality standard, click on the middle image below to load a 57.6 kb image in place of the 10 kb image. | ||

| Photoshop can reduce the image all the way down to its quality setting of zero, for about a 5 kb image (left below). On the right is a 4.6 kb GIMP image. | |
 | |
| If we take it to extremes, Adobe Photoshop users can invoke the blur option and blur the photo to 200% (left below), losing LOTS of detail but reducing the size to 2 kb. A 1.8 kb GIMP image is shown on the right for comparison. | ||

| Of course if the
image is blurred BEFORE saving this will reduce bandwidth for GIMP users. SUMMARY: In all cases GIMP produced an image requiring 5-10% less bandwidth but of comparable or better image quality. | ||
