Very little compression

I have a Photoshop plugin that compresses to about 85% without significant loss of quality, but it’s slow and crashes frequently. This is inconvenient, being that I have thousands of files. This compressor only takes off a few kb (about 5%). Yes so, to reviewer ToNekat, my files we’re not compressed and this app did little.

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?

Lifesaver! 5-Stars!!

This simple little, easy-to-use program saved my job!! When I switched over to Photoshop CC, they left something out of the program that compresses PNG files! There is no fix, so I went in search of something as 90% of my work is PNG files. Seriously, this program reduces these images to where they need to be. LOVE it! I hope you never stop updating.

I don't know why some have problems, but that's true with everything. Sometimes there's other programs that can interfere. Otherwise, this works and I HIGHLY recommend it!
