However, with our own study based on Magento Luma sample images, we found that much higher savings and reduction of file sizes up to 75% and more can be realized while still having decent image quality - see chart and table below. For cases when lossy RGB compression is acceptable, lossy WebP also supports transparency, typically providing 3× smaller file sizes compared to PNG. Lossless WebP supports transparency (also known as alpha channel) at a cost of just 22% additional bytes. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index. WebP lossless images are 26% smaller in size compared to PNGs.

what type of images do you have, how much are your JPG/PNG files already optimized through lossy/lossless compression techniques, what are your quality expectations/requirements.Īccording to Google following file size reductions can be realized with WebP :

The percentage how much smaller WebP images can be compared to JPG and PNG highly depends on your individual case.
