Extract text from Growtopia textures (RTTEX)
To convert RTTEX textures to another format, you need Growtopia or other Game software.
To convert other file formats to the "Game Texture File" file type, you need software like Growtopia or a similar tool.
The .rttex file is a packed game texture format primarily used in Growtopia, a popular sandbox MMO game originally developed by Robinson Technologies and later acquired by Ubisoft. These files store 2D sprites, UI elements, and character textures in an optimized, compressed format generated by the Runtime Texture Packer framework.
The main disadvantage of the .rttex format is that it is a proprietary, compiled game asset. You cannot natively open or view it in standard image editors like Adobe Photoshop or GIMP. Modders, server hosts, and players often need to convert .rttex files to standard raster image formats to edit game graphics or create custom texture packs.
The best conversion targets are PNG (to preserve the alpha channel for transparency) or JPG for simple viewing. However, because .rttex files are highly specific to the game engine, standard online converters fail to read their proprietary headers and rendering data structures. They are closed, proprietary files that often require the original software or community-built unpacker tools to properly read or export the visual data. If our analysis detects a supported underlying or embedded image format within the archive, viewing or conversion may still be possible.
Convert.Guru analyzes your RTTEX file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our RTTEX converter.
