GraphicConverter

One of the best graphics shareware programs out there by Thorsten Lemke, it converts probably all the graphics formats you'll likely to encounter in your lifetime. It not only converts graphics, it's also a mini graphics-editor, although not as powerful or as efficient as photoshop, its useful for quick touch-ups and also launches faster than photoshop.
