Minify JavaScript, CSS, and HTML code to reduce file sizes.

How Code Minifier Works
What is Code Minification?

Minification removes unnecessary characters from source code without changing its functionality: whitespace, comments, line breaks, and redundant syntax.

This reduces file sizes significantly, leading to faster page loads and lower bandwidth usage.

How to Use
  • Select the language (JavaScript, CSS, HTML, or SVG).
  • Paste or type your code into the input field. The minified output updates live.
  • The compression ratio shows how much smaller the output is.
  • Click the lightbulb icon to load sample code for testing.
Supported Languages
JavaScriptTerser-powered: dead code elimination, variable mangling, multi-pass compression
CSSRemoves comments, collapses whitespace, shortens colors and zero values
HTMLhtml-minifier-terser: collapses whitespace, removes comments, minifies inline CSS/JS
SVGSVGO-powered: optimizes paths, removes metadata, shortens colors
Important Notes
  • Always test minified code before deploying to production.
  • Minification is not obfuscation. The code can still be reverse-engineered.
  • Keep your original source files. Minified code is not meant to be edited.
Privacy & Security: All minification runs entirely in your browser. No code is sent to any server.
