Six months or so ago, Felix and I discussed utilities that did a good job of
png compression. pngquant does an excellent job, but there were no packages
for opensuse. I finally got around to packaging it.


pngquant is a PNG compressor that significantly reduces file sizes
by converting images to a more efficient 8-bit PNG format with
alpha channel (often 60-80% smaller than 24/32-bit PNG files).

If you are interested:

Build Service Project:

RPMS 13.1 through Tumbleweed

(pick your release)


It is a cli utility, total installed size ~120k (with man1 man page)


First use on 42.3, 2560x1440 desktop screenshot:
794,229 input 100%
317,290 output 39.95%
476,939 saved 60.05%

No longer nice. Using it on Spectacle pngs, size reduction is nuts, e.g.:
