About Lua Obfuscator

A Lua obfuscator is used to make a script harder to read before you share or ship it. Paste Lua source and get back code with local variables renamed to identifiers like _0xA247, comments stripped, whitespace minified and, optionally, string literals encoded as string.char byte lists. It is best-effort protection that slows down casual copying, not encryption.

Key Features

Strips line and long-bracket comments while respecting strings
Minifies whitespace and removes blank lines
Renames local and local function names to opaque identifiers
Optionally encodes strings as string.char byte sequences
Leaves globals, table fields and function parameters alone, so calls like game:GetService keep working
Each step has its own switch, so you can minify without renaming or encode strings only

Use Cases

Reduce Lua file size for game scripts and configs
Raise the effort needed to casually read shipped source
Strip developer comments before distributing a build
Share a Roblox or Love2D game script with testers without handing over readable source
Obfuscate a config script that ships inside a game build on Steam

Supported Formats

.lua

.txt

Lua 5.1 to 5.4 source

Roblox Luau (turn renaming off if the script uses backtick strings)

Can obfuscated Lua code be reversed?

Partly. Formatting and string.char encoding can be undone in seconds with a deobfuscator, and the DevToolLab Lua Deobfuscator Helper does exactly that. Renamed local variables cannot be recovered, because the original names are no longer in the output, so the logic stays runnable but is slower to follow. Treat obfuscation as a speed bump, and keep secrets such as API keys out of client-side Lua entirely.

Your code stays on your device

Obfuscation runs in your browser with JavaScript. The script you paste or upload is never sent to a server.
