I have experimented on my site. The original, uncompressed icon has a larger transfer volume than an icon that forced compression by making 1 KiB of space characters.
Of course, the difference of only a few bytes doesn’t matter at all. I just experimented with curiosity.
Hi, @salmonspace. The issue with those URLs is that they are already so small we don’t compress them. Files under 1 KiB in size are never compressed by our service.
If there are other questions or concerns, please let us know.
