A good PNG compression utility

[Psych]

I looked through the free software thread and saw Irfanview, and I downloaded it and tried out its PNG compression abilities. I compared it with a GIF image, and the PNG was larger. After a little thinking, I think the reason why is because GIFs work very well with images that have <256 colors, and I think Irfanview is saving the PNG as a 24-bit one. I also base this on the fact that the GIF file is 7/15 the size of the PNG one.

Does anyone know of a utility that will adjust for color range?

Open in Paint, save as JPEG.

Done.

I use GIMP for most of my image editing. Free, and powerful. And it does support the PNG format, though I've not used it.
For lossy compression:
JPG
For nearly lossless compression:
JPG, max quality
Lossless, but compressed:
BMP + WinRAR

I hate how the file sizes vary so much with PNG and GIF. Sometimes PNG is smaller, sometimes GIF is smaller. They are both lossess and fast to decompress. Grr...

RARed BMP is nice, but it is just like a Zipped Tiff.
