Convert images to WebP at build-time
To improve user's experience on the site on mobile devices and/or the Tor network, we should reduce the size of image assets as much as possible. We already compressed the PNGs but further gains could be made by converting images to WebP during the website build. Furthermore, WebP support both lossy and lossless compression, as well as animations, so we'd be able to compress all of our PNG, JPG and GIF lead images to this format.
