I need to reduce a pic size, and convert mp3 files for free. dont like to do that in iTunes or in iPhoto, I want to do that fast with a simple app. any ideas?

Browse opensourcemac.org, you’ll definitely find some good stuff there.

You need to be more explicit. Convert MP3 to what? Re-size what sort of image from what to what? It is all very vague.

You can resize in Preview. There are thousands of free apps to do those things and more on macupdate.

AIFF to mp3 (in audio needs) a Large TIFF or JPEG to a very Small size in jpeg

JUST TO LET YOU ALL KNOW…I ended making a couple of automator services, and they work but I still want apps to batch all of that without the need to use a couple of iApps

I’ve used Photo Drop and it works pretty good. You set your specs, then make a droplet which can be place anywhere…then just drop a photo or folder onto it to process them. Not new, but works.
