UPNG can help. It’s a free image optimizer built for the web and it’s specially designed to optimize PNG files.

They even released a free JS version of the UPNG platform for web developers.
So if you frequently use PNGs then check out UPNG and give it a shot.
The final image output appears on the same page so this works just like a typical webapp. And it’s one of the cleanest I’ve ever used, especially compared to many of the JPEG compression tools out there.
