Spritesheet Splitter

Texture Splitter splits TexturePacker spritesheets into individual frames. It uses a JSON file as input, automatically loads the corresponding PNG, and allows you to reverse a spritesheet into frame-by-frame images without any loss of quality. 

Features:

• Split spritesheets into individual frames
• Create a folder structure based on animations defined in the JSON file
• Resize exported sprites
• Preview animations for each folder
• Runs on Windows and macOS

Installing on Mac

1. Download the file you were given. It will be named something like TextureSplitter.app or TextureSplitter.zip.
2. If it is a .zip file, double-click it to extract it. You should get a file named TextureSplitter.app.
3. Drag TextureSplitter.app into your Applications folder. You can skip this step and run it from anywhere, but moving it to Applications keeps things tidy.
4. The first time you open it, macOS may refuse to launch the app and show a warning such as "TextureSplitter cannot be opened because it is from an unidentified developer" or "Apple could not verify...". This is normal for apps that are not distributed through the App Store.
   • Right-click the TextureSplitter.app file, or hold Control and click it.
   • Choose Open from the menu.
   • A warning dialog will appear again — click Open.
   • If you do not see an Open button, go to System Settings → Privacy & Security, scroll down, click Open Anyway next to the TextureSplitter warning, and confirm.
5. From now on, you can simply double-click the app normally to open it.

Installing on Windows

1. Download the file you were given, such as TextureSplitter.exe or TextureSplitter.zip.
2. If it is a .zip file, right-click it and choose Extract All..., then open the extracted folder.
3. Double-click TextureSplitter.exe to run it.
4. Windows may show a blue screen titled "Windows protected your PC". This is Windows SmartScreen and commonly appears for applications that are not digitally signed.
   • Click More info.
   • Click the Run anyway button that appears.
5. The app will open. You can keep the folder wherever you like, such as your Desktop, and double-click the .exe whenever you want to run it. Nothing else needs to be installed.

Using the app

1. Click the button to choose a JSON file. The matching PNG spritesheet will be found automatically in the same location.
2. Choose a sprite size from the dropdown, or enter a custom size.
3. Choose an output folder. This is where the split images will be saved.
4. Click CUT IMAGES.

You can change the interface language using the button in the top-right corner of the window.

Uninstalling

• Mac: Drag TextureSplitter.app from Applications to the Trash.
• Windows: Delete the TextureSplitter.exe file and its folder if you extracted it from a ZIP archive.

No other files are installed on your computer, so there is nothing else to clean up.
