What is the correct way of converting one or more .png files to .icns files?.

I've installed icnsutils but I'm having a hard time figuring out how to work with png2icns.

You can use:

 png2icns file.icns file.png

The first one is the name you want your .icns file to have. The last one is the .png file you want to export as an icon.

Important: Only convert the icons that match sizes icns supports: (16x16, 32x32, 128x128, 256x256, 512x512 and 1024x1024 pixels)

Or you can use an online service: iConvert Icons

It complains about the size Bad dimensions. I just tried iConvert works fine however,I have to manually select the images one by one, I have to convert over 600 pngs :) . – Uri Herrera Nov 28 '12 at 23:43
Which are the dimensions you are trying to use? Apparently that error is thrown when the size is not supported. The png2icns documentation says: /* Only convert the icons that match sizes icns supports */ which as far as I know are: 16x16, 32x32, 128x128, 256x256, 512x512 and 1024x1024 pixels – M.

Hmm they're 640x640 but I can resize them to 512 and try again, is there a way to batch convert them? – Uri Herrera Nov 29 '12 at 4:00
You can try using this software: RedImages – M. Cunille Nov 29 '12 at 4:07
