JPEG compression typically achieves approximately what ratio?

JPEG compression is a lossy process that trims data to reduce file size by discarding information less important to human perception. For typical photographs saved at a standard quality setting, you’ll often see about a tenfold decrease in data, or a 10:1 compression ratio. Pushing much higher toward 20:1 starts to introduce noticeable artifacts such as blockiness and softening in details, while lower ratios like 5:1 or 2:1 keep more detail but don’t shrink the file as much. So, 10:1 is a common, practical balance between file size and visual quality.
