This is a heavily optimised PNG favicon [0], which is only 192x192. But without trashing the palette, I can't really deduce it further, and it's already 2.7K. Niether pngcrush nor imageoptim can do much with it.

- lifthrasiir 6y agoI tried zopflipng [1] with the very expensive option suggested from the usage and got 2,493 bytes (original 2,740 bytes, nowhere practical as it took 3 minutes) so you don't have to sacrifice the palette, though I'm not sure if 16 or even 4 color palette will significantly alter the visual.

- shakna 6y agoIt's already an 8bit grayscale image - significantly less than a 4 colour palette. And whilst the server might use state of the art compression... There's still no way a much larger image is going to fit in the proposed 1-2K limit.
