Create spritesheets for Starling and Sparrow

TexturePacker: 20 seconds to your optimized sprite sheet


Instead of adding and removing individual sprites TexturePacker allows you to simply add a complete asset folder. Every image that is found inside it will be added to the sprite sheet.

TexturePacker preserves your folder structure in the sprite names inside the data file allowing you to easily group your sprites.

TexturePacker detects all changes and automatically reads the new sprite data when re-entering the application or publishing from command line.

With the powerful command line interface you can simply update all sprite sheets at once.

Trimming / Cropping save space by removing transparency

TexturePacker Trim Crop: remove transparency and minimize texture size

Trimming removes transparent pixels from the border of your sprites. This has two advantages:

  • Reduces texture size
  • Faster rendering

Trimming preserves the sprite's size - the framework needs special support to restore the transparent parts when rendering the sprite.

Cropping in contrast removes the transparent parts - making the sprite appear as if it never had any transparent border.

Alias creation

If two images are identical after trimming only one image is placed in the sprite sheet. The duplicates will just be added to the description file allowing you to access it with both names.

TexturePacker: Auto alias - detect duplicates

This is perfect when using animations: You simply don't have to care about equal phases.

Create heuristic mask

Create heuristic mask creates transparency from images which come with a single key color.

TexturePacker: Heuristic Mask creates transparency

Automatically downscale sprites for all devices

TexturePacker: automated scaling for all devices

Focus on high resolution sprites only while creating your app for devices with multiple resolutions. TexturePacker does all the scaling for you. No need to use an external tool to resize the images.

Using pre-scaled sprites keeps the frame rate high and reduces runtime memory consumption.

  • Reduce memory consumption
  • Increase performance
  • No additional work required

Layout algorithms and packing features

TexturePacker has 2 layout algorithms:


  • Best for tilemaps and simple animations
  • Sprites are placed in a row until the row is full
  • Sort the sprites by name, width, height, or area

This algorithm is FREE and can be used for all projects.


  • Best-known algorithm for packing textures
  • Is fast and has a high packing ratio
  • Enable rotation and trimming for best results (depending on your target framework)

This algorithm is available in TexturePackerPro.
