TexturePacker

TexturePacker is a graphic design utility app that can help texture artists to streamline the process of sprite sheet generation, with automated support for high-resolution images, scaling, and publishing of finished projects to all compatible devices in a single click. The app supports importing of all the major image formats (PSD, PNG, TGA, JPG, TIFF, BMP, and SWF), file or folder drag & drop import, automatic collection, and organization of sprites (with preserved folder structure as part of the sprite names).

TexturePacker is able to pack multiple sprite sheets at once, create additional sheets to make a place for all your sprites, sort the sprites into specific categories (characters, backgrounds, trees, etc.), and much more without straining both your and client system. By utilizing Texture Packer Tool, your visual, interactive, or gaming project can reduce the number of files it requires to load, reducing the strain on client systems, save memory resources, increase framerate, make animations run smoother, increase game boot times, and preserve visual quality even after all your sprites go through effective compression.

The app can also trim and crop your sprites, thus reducing their texture size, reducing the size of your sprite sheets, and enabling faster rendering of 2D art.  Other features include better handling of repeated sprites (all still accessible with their original name), creation of transparency masks, and two layout algorithms.

If you are a game developer whose games have extensive sprite use, TexturePacker will be a perfect app for you. To provide a more streamlined experience for game developers, It has built-in support for all major 2D-focused multiplatform engines currently in popular use. This includes Unity, HTM5/CSS Sprites, Cocos2D, SpriteKit, Starling, Sparrow, LibGDX, and many others. Textures can be encrypted with fast, reliable, and secure algorithms, and the integrated support for game engine exporting can be expanded with the use of customized export formats.

In addition to yearly or lifetime license purchases, the Texture Packer app can also be tested via a FREE trial.
