Quick and easy-reminds of me of Irfanview

Ive been searching for a utilty that works like Irfanview in Windows. I own a lot of powerful software, Photoshop included, but frequently I just need to do something fast, say, converting a TIFF (from a screen grab) to a Jpeg. This does it really well. No hassle, no delay, totally straight-forward.
