DESCRIPTION

PNGCrusher is a simple app that optimizes the filesize of PNG images. Just drag any number of PNG files onto the app and they will be processed by the open source OptiPNG, which provides better compression rates than the standard pngcrush. If you deal with png images a lot, especially in web development, this app could save you time and bandwidth!

Note: Not all PNGs will see a noticeable change in filesize. Some are already as compressed as they can get.

Caution: PNGCrusher replaces your original files with optimized ones, but only if the compression can be improved. All of the caveats of OptiPNG also apply to PNGCrusher.

GENGIS  Simply it does what it says. The compression is very effective. I use PNGCrusher to compress the PNGs I include in the help documentation of my software. I visited the developer's site and read about how it is built; this is a very simple application, but it works well and is very useful, so thank you for it!

GARRETTMURRAY  I've created a new version of this app (also under the GPL) which is targeted at Intel Macs only and starts up much faster due to a recompiled OptiPNG build:

HAUBERG SOFTWARE  Really Nice app. One thing I'd really like to see is the ability to first launch the app and then have the ability drop files onto it. That is, when the app is launched without any pngs dropped onto it a window should be shown onto which the images could be dragged.

The way it works now is a little inconvenient because you have to locate the app in finder in order to use it unless you have it in your dock. It doesn't work well with application launchers

This would really be the finishing touch on this marvel :-)

JOBBY  You could drag it to your Finder sidebar or toolbar, then you'd always have it handy (unless you were working from the Desktop, of course).

Agree it would be nice to have a floating window if you just run it on its own, though. I'd also like it to not break the icon — after I pass a PNG through PNGCrusher, it just has the generic PNG icon rather than the preview of the file contents, and I have to use Pinki to restore the preview...

BENZENE  Slick little program. Does what it says, and makes no fuss about it. I use it for all the pngs on my site, I've seen it trim a 192K file to less than 64K without any degradation. Sweet.

ANONYMOUS  Why the pngcrush algorithm isn't part of every imaging package that produces png is a mystery to me. A drag-n-drop GUI for it is just icing on the cake.
