See also T255913: Document tagline and icon options of $wgLogos by putting them in the installer, it would be nice if this information was available before the MW-1.35-release.

I've added instructions on https://wikitech.wikimedia.org/wiki/Wikimedia_site_requests#Change_the_logo_of_a_Wikimedia_wiki based on the lossy version of the logos I've just deployed to production. I recommend that you get the desktop improvement versions of the logos through the same bit grinder.

I guess that since the logo is separated out, that's just https://en.wikipedia.org/static/images/mobile/copyright/wikipedia.png for all Wikipedias, right?

Yes, I was going to say — we're using SVGs aside from the globe (and some other project icons). Is there anything we need to do with the SVGs?

Seems like this tool could help strip useless content (like comments) from SVGs if there's any: https://github.com/svg/svgo

I've just tried it on the French Wikipedia word mark SVG and it reduced it from 16.292kb down to 6.08kb

The tool has a lot of options, you'll need to double-check that it doesn't have defaults that are bad for our SVGs.
