Extract text from Lua bytecode files (LUC)
To convert LUC bytecode files to another format, you need Lua Interpreter or other Developer software.
To convert other file formats to the "Compiled Script Bytecode" file type, you need software like Lua Interpreter or a similar tool.
The .LUC file contains compiled Lua bytecode. Developers use it in game engines, embedded systems, and mobile applications to execute scripts faster and with a smaller memory footprint than parsing plain text LUA files. It is executed natively by the Lua Interpreter and can sometimes be reverse-engineered using specialized open-source decompilers like unluac or luadec.
Because .LUC is a compiled binary format, it is not human-readable. You cannot open or edit it directly in a standard text editor like Notepad++. It is also heavily dependent on the exact version of the compiler; .LUC bytecode compiled for Lua 5.1 generally will not run on Lua 5.3 without a compatibility layer. Furthermore, many game engines apply custom modifications to the bytecode structure, making standard parsing impossible.
The only practical conversion target is back to LUA (plain text script) or TXT. However, be aware that decompilation is fundamentally lossy. The original code formatting, developer comments, and local variable names are permanently discarded during the initial compilation phase.
This file format is exceptionally difficult to convert because standard online document converters lack the reverse-engineering algorithms required to interpret version-specific bytecode. Often, only specialized command-line tools can properly read or export the data. Despite these limits, just drag and drop your file to convert.guru to identify the format, view it, and convert it when possible. Our platform can inspect the file's binary header to confirm the Lua version and extract readable text strings embedded in the compiled data.
Convert.Guru analyzes your LUC file, detects the exact format, and lets you read the text inside.
Users also converted LUAC, CLU and PHB files.
If you want to convert LUC file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Lua Interpreter or similar software from the "Compiled Script Execution" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to LUC, try Lua Interpreter or another comparable tool in the "Compiled Script Execution" 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 LUC converter.
