• Extract Original: Save original textures as .png or .tga files.
  • Option to remove alpha channel when saving PNGs.
• Replace Texture: Easily replace existing textures with your custom images (supports various formats like PNG, JPG, TGA, etc.).
  • Automatic resizing to fit the original texture dimensions.
  • Handles transparency correctly.
• Restore Original: Revert textures back to their state from the last saved backup.

⚠️ Important Notes ⚠️

False Positive Virus Detection:
This application is built using Python (with PyInstaller), which may trigger false positive detections from antivirus software.
There is no malicious code or virus intentionally included. However, if you’re concerned, feel free to avoid using the tool.

SPT Use Only:
This tool is designed exclusively for use with SPT (Single Player Tarkov).
❌ Do NOT use this on live Escape from Tarkov files.
Modifying live game files can lead to corrupted installs and will likely result in a BattlEye ban.
You have been warned.

Backups:
Always back up your original game files before making any major modifications, even though this tool includes a built-in backup system.

.assets/.resS File Handling:
When editing .assets files, ensure the corresponding .resS files are in the same directory.
Otherwise, texture data may not load or save correctly.

🛑 Mod Submission Guidelines Reminder 🛑

According to the SPT File Submission Guidelines:

• You must not upload bundles that replace original EFT or SPT files.
• File overwriting and other destructive edits are forbidden.
• All changes must be applied at runtime using the mod loader.

This tool is a standalone asset editing utility, not a mod.
While it enables creation of custom bundles, users are fully responsible for how they use or share those files.
If you plan to submit any content to the SPT Hub, make sure it follows the official guidelines.
