## JPEG Compression

The amount of compression (quality of image) for a JPEG image can be chosen (from a scale of 0 to 100). The image quality is inversely related to the amount of compression since the compression algorithm is "lossy".

Properties | Image

Quality: 80 34.1 kb |
Quality: 70 26.0 kb |
Quality: 60 22.4 kb |
Quality: 50 17.0 kb |
Quality: 40 14.3 kb |
Quality: 30 6.97 kb |
Quality: 20 4.80 kb |
Quality: 10 3.75 kb |
