I've taken the liberty of putting hedwig's image assets though a range of optimisation tools. Image optimisation allows us to reduce the footprint of images - meaning faster load times at no cost to image quality. It does this by finding the best (lossless) compression parameters, stripping embedded comments, and removing unnecessary colour profiles. See more.
I found 10 optimisable images, making a 275 KB reduction in size. That's about 14.10% of your total image assets.
Tools used: advpng, gifsicle, jpegoptim, jpegrescan, jpegtran, optipng, pngcrush, pngout. This is an automated bot maintained by @skattyadz
