This is a site/utility that I use a lot: https://jakearchibald.github.io/svgomg/
It allows you to take SVG files and optimize them further. On average, I've found that the SVGs used on this site are 25% larger than they need to be. Hopefully not for long, and I hope this tool helps you all out similarly as well
I meant to ask: is this lossless or lossy optimization?
I have no idea! I threw a large SVG at it that had more details, and the end result seemed identical when I zoomed in. That doesn't conclusively answer anything (haha), but that is one piece of data
