A little late (half year xD).

The script is very useful for using pngcrush. I’m using it to reduce the size of hi resolution zelda images. Yeah!

But I’ve had problems with file names containing spaces. This little modification can do the trick.

#!/bin/sh find $1 -name "*.png" | while read png do echo "crushing $png" pngcrush -brute "$png" /tmp/temp.png mv -f /tmp/temp.png "$png" done;

Not sure if it’s because of a mac or something but I don’t think it should take 10 minutes. On my windows machine the operation was almost instant.

@jay: Acorn on the Mac uses pngcrush when you save a png for the web.

@David Walsh: pngcrush works just fine on Windows too.

So… there a way for non-command line folks to do this via a drag / drop app?

I did a comparison of 8 free image optimizer tools, the post is in Spanish but the comparison chart is very easy to understand.

@paul: Try punypng.com

I tried PNGCursh and Smush.it on an uncompressed PNG of 93Kb.

Results
PNGChrush: 90Kb
Smush.it: 87,32Kb
PS Save for web: 87,06Kb

I used the following command line for pngcrush: pngcrush.exe -reduce -brute -e 2.png “%1″

Maybe I am doing something wrong?

Hassan: Grab Cygwin and install PNGCRUSH on that. Or you could just use Smush.It.

This is great, but, what about Windows users?
