I'm attempting to batch process some images using pngquant and I have realized I don't really know what I'm doing. I'm on a mac and I can navigate to the executable and open it, but after that I can't access any of the functions/features of pngquant.

Basically, I've gotten to the point of ./pngquant, but don't know what to do after that. Any help from anyone?

I've got a couple hundred images to run through, so it would be nice to not have save each of them individually...

  • Similar, but most definitely NOT a duplicate. OP is asking for someone to help him understand how to use pngquant in the terminal, not necessarily how to go deep into a file directory—the question is more basic than that.

If it were me, I would use Tiny Png It does essentially the same thing. (I am very unfamiliar with using the terminal as well.)

What exactly are you trying to process?

Here is an example on usage:

./pngquant 256 ../test/*.png

I am running the command from the pngquant directory and pointing it to my test directory where I have all my png files....

  • I believe the OP is unfamiliar with how terminal works and is asking for a detailed "how to".

I would recommend pngquant to osx with the help of Homebrew (which you need to install first)

brew install pngquant
cd path/to/your/images
pngquant 256 *.png (all png-images)

You can use Batch tool like a link!Acc image batch process[a panda][1] this can dealwith png,gif,jpg and some other
