Lua Minifier & Compressor Online
Use this online minifier and compressor to reduce Lua script size and speed up load times. Write, paste or upload your .lua file and choose safe compression options. The tool removes non essential characters and can shorten local names when requested while keeping runtime behavior intact.
Core Features
- Minify Lua by removing comments and redundant whitespace
- Compress by collapsing expressions
- Optional local name mangling to shrink identifiers for extra savings
- Safe presets that avoid renaming globals or library calls used by frameworks
- Runs in the browser so your code never leaves your machine
How to use this Lua compressor
- Write, paste or upload your Lua script into the editor
- Choose optimization options fro your Lua code
- Click Minify Lua button for minification and compression
- After minification, copy or download the minified script in .lua file
Why Minify And Compress Lua?
- Smaller Lua files reduce transfer time for remote scripts and embedded systems
- Reduced size helps when distributing assets to constrained devices
- Compression lowers memory footprint in environments that load scripts repeatedly
- Minified builds are useful for production while keeping readable sources for development
Lua Minifier Examples
Example 1: Simple function
Formatted Lua
-- Compute factorial local function factorial(n) if n <= 1 then return 1 end local result = 1 for i = 2, n do result = result * i end return result end print(factorial(5))
Minified Lua
local function factorial(n)if n<=1 then return 1 end;local result=1;for i=2,n do result=result*i end;return result end;print(factorial(5))
Example 2: Lua Minification with Local Mangling
Formatted Lua
local users = { { id = 1, name = "Alice" }, { id = 2, name = "Bob" } } local function names(list) local out = {} for _, u in ipairs(list) do table.insert(out, u.name) end return out end for _, n in ipairs(names(users)) do print(n) end
Minified Lua
local a={{id=1,name="Alice"},{id=2,name="Bob"}}local function b(a)local b={}for a,a in ipairs(a)do table.insert(b,a.name)end;return b end;for a,a in ipairs(b(a))do print(a)end
Customization options
This Lua minifier tool has below customization options available to optimize the scripts.
Option | Default | Description |
---|---|---|
Rename Variables | False | Rename local variables to shorter names for smaller code |
Rename Globals | False | Rename global variables to shorter names for size reduction |
Simplify Math | False | Simplify mathematical expressions where possible |
Best Practices For Lua Minification
- Always validate Lua code before minifying
- Keep a backup of original Lua files
- Use minified Lua only in production
- Combine minification with Lua obfuscation if needed
- Test performance after compression
Conclusion
This online Lua minifier and compressor provides a fast and safe way to shrink scripts efficiently. Minified builds make distribution and loading more efficient while keeping source versions readable in your repository.
