While there is no definitive and exact figure for how much data you will save by optimizing your images using Lossy or Lossless compression, the following examples should serve as a good guide.
To test out the kind of results that could be achieved, the same image was compressed using both the Lossy and Lossless method. The results are as follows:
With Lossy compression enabled, the sample image was compressed from 230.26 KB to 64.92 KB, giving an almost 75% reduction in size.
With Lossless compression enabled, the sample image was compressed from 230.26 KB to 172.18 KB, giving just over 25% reduction in size.
For more detail on the compression process and the results achieved, take a look at the “Lossy vs Lossless image compression – A guide to the trade-off between image size and quality” blog.
