Customer Reviews

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

Great app, ignore bad reviews

I use Photoshop Elements and it doesn't do ANY compression when it saves PNG files, so the resulting files are laughably big--often several TIMES bigger than they need to be.

Before using this app, I would re-open the files in GIMP one-by-one and re-save them to compress them, which is awkward and time-consuming. Now that I have this app, I can compress files in seconds. Kudos to the developer for making such an effective and easy-to-use app.

To all the people complaining that it doesn't compress your files, did it ever occur to you that maybe they're already correctly compressed?

Better Than I Thought

Before I bought this I honestly thought that it wasn't worth the $5. However, after duplicating my 18MB picture folder and simply dumping it into this app within 5 minutes I shaved off 3MB. You can change the settings so that it saves the pngs as the same name so you can drag it back into the application you're using it for and replace the old ones. Now my iPhone app is farther away from the WiFi-only 20MB limit, which will help my app sell more.
