Except that, as Eric pointed out, it doesn't save any space at all.

    $ ll *.png
    -rw-rw-r-- 1 gary gary 454 Dec  7  2018 hi16-action-make.png
    -rw-rw-r-- 1 gary gary 425 Dec  7  2018 hi22-action-make.png
    -rw-rw-r-- 1 gary gary 226 Dec  7  2018 vim16x16.png
    -rw-rw-r-- 1 gary gary 347 Dec  7  2018 vim32x32.png
    -rw-rw-r-- 1 gary gary 474 Dec  7  2018 vim48x48.png

Note that each file is less than 512 bytes, the smallest block size
that I'm aware of.  The block size on my hard drive is 4 kB, so each
file easily fits within one block.

    $ du -sh *.png
    4.0K    hi16-action-make.png
    4.0K    hi22-action-make.png
    4.0K    vim16x16.png
    4.0K    vim32x32.png
    4.0K    vim48x48.png

So, compressing them will not have any effect at all on disk-space
consumption.

Something else you should consider is that, on my system,
/usr/local/share/vim/vim90 consumes 41 MB and the *vim* files in
/usr/local/bin consume 21 MB.  Out of 62 MB, 1.7 kB is
nothing--definitely not worth doing _anything_ about.

Regards,
Gary
