Extract text from game text files (FMG)
To convert FMG text files to another format, you need WitchyBND or other Game software.
To convert other file formats to the "Game Localization Data File" file type, you need software like WitchyBND or a similar tool.
The .FMG file format is a compiled binary text format primarily used by the FromSoftware proprietary game engine (used in titles like Elden Ring, Dark Souls, and Armored Core) and the Unreal Engine 4 implementation of Tales of Arise. It stores localized in-game text, UI messages, item descriptions, and dialogue strings.
Because it is a closed, undocumented game asset, you cannot simply open an .FMG file in standard text editors like Notepad. Doing so will display unreadable formatting and corrupted characters. Modders and translators heavily rely on community-developed software like WitchyBND or Yabber to properly unpack and edit these files.
The main disadvantage of the .FMG format is its rigid, highly specific binary structure. It compiles readable text alongside strict internal offset tables and string IDs. Editing the binary directly often breaks these offsets and immediately corrupts the game upon loading. Standard online document converters completely fail to process .FMG because they cannot parse the proprietary offset dictionaries.
For modding or translation purposes, the best target formats for conversion are XML or JSON. These standard formats make the string IDs and actual text pairs safely human-readable. Once edited, they must be converted back to the original .FMG container for the game engine to read them.
This file format is exceptionally difficult to open or convert because it lacks official developer documentation and is intended strictly for engine-level access. We can identify the file format, inspect the binary file, and show embedded text or internal content. If our analysis detects a supported underlying structure, viewing or conversion to XML or TXT may still be possible.
Convert.Guru analyzes your FMG file, detects the exact format, and lets you read the text inside.
Users also converted GMI, SRK and NUT files.

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 FMG converter.
