you can do the same with one line in imagemagick :)

I used in an old project to create color palettes in artworks and worked quite well

But...If you want to do it very quickly and not deal with the quite dense ImageMagick docs this is way easier.

When I want to do this and something else, two hours reading the ImageMagik documents will save me six hours of trying to remember this site and Googling around for a free service that does the other thing...and probably two hours of getting them to work together as a pixel pipeline.

Or at least that's what I have realized about reading documents over the past year and a half...Google lets me avoid reading documents it does not save me time.

This is why I don't let myself become dependent on random internet services[1]. Apps on my machine only change or go away when I want them to.

[1] No offense to the site maker - the palette extractor is cool!

I think the site is great too. ImageMagiK's output is not quite as self explanatory nor visually appealing. Since I deal with hundreds of images at a time, though, I have learned to think in terms of a pixel pipeline.

I also try to avoid the overhead of managing emails and passwords.

convert path/to/img -colors 16 -unique-colors txt:-

That is really simple.
