📜 JS Minifier – Minify JavaScript Online Free

Large JavaScript files slow down your website. Our JS Minifier removes whitespace, comments, and renames local variables to create a compact, production-ready JS file. Uses the industry-standard Terser engine.

⚙️ Minification Techniques

• ✅ Remove whitespace & line breaks
• ✅ Strip comments (except legal)
• ✅ Rename local variables (mangling)
• ✅ Remove dead code (optional)
• ✅ Concatenate strings

📊 Before vs After Example

💻 Code Example

// Before
const hello = function(name) {
  console.log("Hello, " + name);
};
hello("World");

// After minification (with mangling)
const hello=function(o){console.log("Hello, "+o)};hello("World");
