Interesting... can you ballpark the percent improvement folks would expect to see between the most well-known image tools or libraries available now?

- fps_doug 8y agoI suggest you just try running optipng on some random PNG files you have on your HDD. Results vary greatly, but I've seen savings between 10 and 20% on files coming from GIMP where I always set the compression to 9 (maximum). I never touched Photoshop in my life so no idea what you can tune there and what its defaults are, but general experience shows that a lot of people either just don't bother and go with the defaults, or go all crazy clicking and manipulationg everything without knowng what's going on. I agree with you that for JPEG there is no silver bullet, but like that other comment here suggests, you could perfectly just run optipng on max settings in a cronjob and call it a day, because you know there will be absolutely no quality loss if you don't explicitly request it.
- MaxBarraclough 8y agoHere's a blog post that compares them. Apparently the difference can be pretty extreme: http://daleswanson.blogspot.com/2013/08/a-comparison-of-png-compression-methods.html http://daleswanson.blogspot.com/2013/08/a-comparison-of-png-...
