TexturePacker can help you pack sprites and export them for all devices. The program can do this by creating sprite sheets or collection of graphics with various resolutions, which are mostly used in games. The product is not intended for the general user, and even if you have some experience with this type of software, you will probably need to consult its extensive documentation, which includes various tutorials.
The tool has an easy-to-use interface. There is a working area onto which you can drag and drop image files and a panel on the left that allows you to change settings. Images can be opened individually but it is probably better to import them in batches, as complete folders. Luckily, the program has a wide support of image formats, including PNG, BMP, JPG, PSD, TGA and TIFF. Moreover, Flash animations (SWF) can also be imported and they appear as folders. It is also quite convenient that the tool preserves the folder structure as part of the sprite names.
TexturePacker can automatically downscale sprites in such a way that they are optimized to be used in all types of devices without affecting their visual quality. Besides, it allows you to perform operations like trimming, which is intended to remove transparent pixels from the sprite border. This contributes to reducing texture size and consequently speeds up rendering.
Good news is that TexturePacker allows previewing the results before you finally export them. In my opinion, the best advantage of this product is derived from its support of a long list of game engines, including but not limited to Unity, Cocos2D, SpriteKit, Starling, Sparrow, LibGDX and Moai. It is also quite practical that it can export HTML5 / CSS sprites as well.
In general, TexturePacker can have a significant impact on simplifying the work with sprites, which usually takes a lot of time and effort. The product is downloaded as a single file, but it requires the users to choose whether they want to use the free version or try the Pro features.
