I wanted to share ShoeBox a free app that works on Windows and Mac computers. There are lot of sprite related tools in it such as sprite packing, extracting, animation sheets or bitmap fonts. All of the export formats can be customized and come with several templates such as NGui, Cocos2d, starling, sparrow, html5 etc.

Some of the tools that I use for my game development:

[size="5"]Sprite packing

Packs multiple images, SWF files (AS1, AS2 or AS3) or animated GIF animation's into one texture Atlas

[size="5"]Animation to Sheet

Converts a animated GIF or SWF (AS1, AS2 or AS3) into a sprite sheet with an array of frames.

[size="5"]Sprite Pivots

Sprite Pivots lets you edit registration points (pivots) of multiple sprites at once.

[size="5"]Bitmap Font

Creates a anglecode compatible *.fnt bitmap font. The way this tool is different from others is that it lets you fully customize the font for example in Photoshop.

[size="5"]Extract Sprites

Detects sprites in a transparent image and cuts them out. This is useful if you have a sprite sheet or asset that contains already several sprites but want to separate them into single image files.

[size="5"]Extract Tiles

Extracts a tile map and tile bank out of a screenshot of a game. The result can be saved as a Tiled *.tmx map file and a tile-bank *.png image.

Any requests or suggestions are also welcome on the uservoice page:

Some of the games at my work (Soap) are done with this tool, some featured examples that used either the sprite extraction, pivot tools or sprite packing:
