→ Use RTPackJS (programmable, supports both encode and decode)
While this guide focuses on , the tools mentioned are often bidirectional. This is essential for game modification: after editing a converted PNG, you may want to pack it back into the .rttex format for the game to use. Both RTPackJS and the original RTPack tool (from the Proton SDK) provide functions for this purpose, allowing you to convert a PNG (or other standard image) back into the proprietary .rttex format.
If you are a game modder, asset extractor, or reverse engineer, you have likely encountered the .rttex file format. Commonly used by Robinson Technologies in games like Growtopia , this proprietary format stores compressed texture data. However, standard image viewers and editing software cannot open it. rttex to png
The converted PNG images will appear alongside your original RTTEX files, ready for viewing or editing.
For a quick, software-free conversion, several web-based tools can handle RTTEX files: → Use RTPackJS (programmable, supports both encode and
Unlike universal formats like PNG or JPEG, RTTEX is a specialized container designed for the Proton engine
: A repository containing an HTML-based converter interface that handles both RTTEX to PNG and the reverse. 3. For Developers (Programming Libraries) If you are a game modder, asset extractor,
Developers need to audit textures for visual artifacts, sizing issues, or alpha channel errors. PNG provides a lossless representation of the original art.
Select PNG as your desired output format. Ensure "Preserve Alpha Channel" is checked if your textures require transparency.
