① Compression rate

The file size of JPEG-compressed image depends upon the actual content of the image. Images

containing much detail will generate larger files. Image quality is controlled through the level of

compression; where, high compression yields small files, while low compression maintains higher

image quality at the expense of larger files. The table below contains compression ratios for each step,

derived from real-life tests:

Compression Rate Level 1 Level 2 Level 3 Level 4 Level 5

QVGA 15 18 21 24 27

VGA 15 20 25 30 35

Level 6 Level 7 Level 8 Level 9 Level 10

30 33 36 39 42

40 45 50 55 60

1 2 ... 28 29 30 31 32 33 34 35 36 37 38 ... 70 71
