Extract text from Multilingual interface files (MUI)
To convert MUI Language files to another format, you need Microsoft Windows or other System software.
To convert other file formats to the "Localization Resource File" file type, you need software like Microsoft Windows or a similar tool.
A .MUI file primarily stores Multilingual User Interface resources for Microsoft Windows. It contains localized text strings, dialog boxes, menus, and interface elements for a specific language, allowing the operating system to switch languages without replacing the core software executables.
Technically, these are compiled binary files based on the standard Portable Executable (PE) format used by EXE and DLL files, but they lack executable code. Because they are compiled, they cannot be edited or viewed in standard text editors. Users typically need to convert or extract the contents of a .MUI file when translating software, modifying Windows themes, or diagnosing application localization errors. Modifying them requires specialized software like Microsoft Visual Studio or Resource Hacker.
To translate or analyze the localized text, the best target formats for conversion are RESX, XML, or plain TXT. However, extracting this data is difficult because .MUI is a proprietary, closed system format requiring specific memory mapping to parse the internal resource tree. This is exactly why standard online document converters fail to process it.
Convert.Guru analyzes your MUI file, detects the exact format, and lets you read the text inside.
Users also converted EFI, DLL, MANIFEST, EXE, PNG, DMG, TXT, BIN, WMA and POW files.
If you want to convert MUI file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use Microsoft Windows or similar software from the "Multilingual Interface Resources" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to MUI, try Microsoft Windows or another comparable tool in the "Multilingual Interface Resources" category.
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 MUI converter.
