I cannot tell what language you are implementing in from the site, but if you are using C or are able to interface with C, you can easily just drop in QOI, QOIG, or RPK codecs as they are Quite Small. If you are planning to use images with only a few colors or large swaths of the same color, I would strongly recommend using RPK over QOI, as it will give Better Compression and Decode Slightly Faster.
