Graphics formats supported include BMP, GIF, TGA, as well as further compressesing PNG files by removing unnecessary data without affecting quality. Animated GIF and PNG files (APNG) are also supported.

Agree, 65% processor time and start after 2 minutes on P4/2GHz? No way, this PngOptimizer must be optimized.

Just downloaded 1.8 - same problem. Nothing's appeared and processor is using 100% on one core. Three minutes now so it'll have to be killed.

.. with just a few random characters like the asdf example in 'PngOptimizer.ini' .. the new update works great on Win98 (or the whole ini template)

This program is great for general PNG compression, but for web graphics that will see many downloads over time, I use RIOT (http://www.portablefreeware.com/index.php?id=1821)
V2.0
