Review by 12buckleshoe

did exactly what I needed - There are a number of free terminal mode or web based png compressors, and a few stand alone ones here on the app store. I've tried all I've found, and yes, the terminal based fast ones are faster running that this one, but it can be a bit of a pain, especially if you aren't used to scripting. The web based compressors are fairly painless and they do work, but this app is faster, easier, and compresses better than the web based versions I've found. A caveat, I'm only compressing photoshop png's, so my results may not be yours. But for my needs today, "PNG Compressor" fit the bill. An example: mostly transparent image: orig=196kb , another app store program=196kb (!) web based=133kb, this app's result=76kb

Looses alpha transparency - Converting a 24-bit PNG to 8-bit isn't my idea of "lossless" compression, especially when it doesn't even let you specify the matte color (seems to just turn everything up 100%?) when you have semi-transparent pixels in your image.

Not worth the money - It doesn't strip PNGs of Fireworks data. In fact it doesn't appear to reduce PNG file size as all. If so the reduction is negligable. This is a waste of money and is nowhere near as good as other tools you can find that actually do what this claims to. Search a bit and get another tool, this one won't satisfy and IMHO should be pulled from the market as it simply doesn't work as advertised.

Meh - Bought this, threw two PNGs into it (which I had been able to reduce by hand at least 10% in Photoshop by tweaking the color palette) and… 0% reduction. Not recommended.

Perfect - Compressed a bunch of PNGs I made in Acorn- most decreased in size by around 20%. Improved my Google Insights score signficantly. This app does exactly what it promises, and worked well for my needs.

Review by Thomashornb

Did not compress well, 1% compression at best - I had a bunch of web graphics ranging from 50KB to 900KB, when I ran this on my images I got no noticeable change in over 50% of the images. I got a 1-2 KB reduction in the rest.
