About TFM files
A .TFM file is predominantly a serialized game save data file created by the Unity game engine. It stores critical game state information, such as player progression, inventory items, and world configurations. Secondarily, .TFM extensions are used as Insight Toolkit (ITK) Transform files for medical image registration, obsolete FormTool Gold electronic forms, or TeX Font Metric files. The main disadvantage of the .TFM format is its highly proprietary nature. Unity game saves are typically compiled into a custom binary format or encrypted to prevent tampering. This means a .TFM file exceeds the capabilities of standard web browsers and text editors, locking your data into a closed software ecosystem. Users frequently need to convert these files to structured formats like JSON or XML to debug, mod, or manually edit game save data. However, converting this file is exceptionally difficult because standard online converters lack the specific game's original deserialization logic. Often, only the original game or a community-built save editor can safely parse the data without corrupting it. Just drag and drop your file into convert.guru to identify the format, view its internal hexadecimal or text content, and convert it when an underlying format is supported.
Convert.Guru analyzes your TFM file, detects the exact format, and lets you read the text inside.
If you want to convert TFM file to TTF, OTF, WOFF, WOFF2, EOT, SVG, BDF, PCF, FNT, FON, PFM or AFM, you can use Unity or similar software from the "Game Save Serialization Data" category. In the File menu, look for Save As… or Export….
To convert UFO, WOFF, PFB, GXF, AFM, F3F, SFD, WOFF2, PSF, TTF, TXF or OTF files to TFM, try Unity or another comparable tool in the "Game Save Serialization Data" category.
The TFM 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 TFM converter.
