I’ve used pngcrush to reduce the size of PNGs produced by Photoshop. It’d be neat if there was a plug-in for Photoshop that ran pngcrush automatically on PNGs when saving them for the web.

Is there such a thing? Is such a thing possible? (I don’t know what limits there are on what Photoshop plug-ins can do.)

There are two such options: One free and one payware

SuperPNG is freeware PNGoutwin is payware

Better yet use R.I.O.T. albeit not from within photoshop. No interwebs access required per use.

As far as I can tell, PNGoutwin isn’t a Photoshop plugin. But SuperPNG looks great. – Paul D. Waite Sep 16 '10 at 12:12

No there's no such plugin for Adobe Photoshop. Why don`t you use Smush.it ?

Looks worth comparing with pngcrush. It’d be nice to have something baked into the Photoshop saving workflow. – Paul D. Waite Dec 8 '09 at 21:10
