I just realized that the PNG file for the logo hosted on wikimedia, is 232KB! That is a lot, that's unnecessarily large for such a simple logo, so I used vtracer, a raster image to SVG vectorizer, written in Rust, and SVGO, a SVG optimizer, to create the SVG file version of the logo, it is 16KB. a 93.1% improvement in size! (and they look the same)

The 2 commands used:

Makes you think how much the Wikimedia Foundation can improve the loading experience for users and save in bandwidth costs, if they optimize all the PNG raster images that can/should be optimized, which this file is a prime example of.

I think it's up to the users themselves, who sometimes also write bots like this. I have encountered a lot of such effort when clicking on an image, especially on the more popular ones. As an example, check this out: https://commons.wikimedia.org/wiki/File:Tux.svg
