Convert T3 to another file type
To convert T3 games and configs to another format, you need TADS or other Game software.
Convert a file to T3
To convert other file formats to the "Text Adventure Game File" file type, you need software like TADS or a similar tool.
About T3 files
A .t3 file is typically a compiled interactive fiction game created with the Text Adventure Development System 3 (TADS 3). Less commonly, it serves as an access control system data file for Mircom TX3 Series hardware. TADS 3 files contain compiled bytecode, meaning the human-readable game script has been transformed into a machine-readable format meant to be executed by a game engine. Mircom files store proprietary building configuration data, structured using standard GZIP compression.
To play a .t3 game file, you need a specialized interpreter such as Gargoyle or QTads. These programs act as virtual machines that read the compiled game logic and render the text interface. For the Mircom data files, administrators use the official Mircom TX3 configuration software to deploy access control settings to building panels.
Users often attempt to convert .t3 games into standard text documents like PDF or DOCX to read the story, or try to convert Mircom files to CSV for easy editing. This is highly disadvantageous. A .t3 game is not a simple text file; it is an executable program. Converting it to a static document strips away all interactivity, conditional logic, and game state variables. Standard online converters fail completely here because they do not possess the specific virtual machine engines required to decompile the bytecode.
The most pragmatic solution is extraction rather than traditional conversion. If you have a Mircom .t3 file, you can often extract its contents into readable XML or raw data since the underlying format is GZIP. For TADS 3 games, reverse-engineering the compiled code is practically impossible without the original author's source files.
Because this file format is essentially a closed, proprietary executable or hardware dataset, conventional format conversion is ineffective. However, you can still use convert.guru. Just drag and drop your file to identify the exact format, view its internal hex data, and check for embedded text. If our analysis detects the supported GZIP structure within a Mircom dataset, viewing or extraction may still be possible.
Convert.Guru analyzes your T3 file, detects the exact format, and lets you read the text inside.
If you want to convert T3 file to EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP, SAV or DAT, you can use TADS or similar software from the "Interactive Fiction Game Executable" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to T3, try TADS or another comparable tool in the "Interactive Fiction Game Executable" category.
The T3 Converter Story
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 T3 converter.
