Code Minifier

Minification removes unnecessary characters from code — comments, extra whitespace, newlines, and optional syntax — without changing functionality. This reduces file size, leading to faster downloads and improved page load performance.

No. Minification rewrites code to be smaller while keeping it valid and executable. Compression (like gzip or Brotli) is a separate step that encodes the file using algorithms. For best results, use both: minify first, then serve compressed files.

This tool performs safe, conservative minification: removing comments, collapsing whitespace, and stripping unnecessary characters. It does not rename variables, rewrite logic, or perform advanced optimizations that could alter behavior.

Currently JavaScript, CSS, and HTML are supported. Each language has tailored rules — for example, JS comment removal handles both single-line and multi-line comments, CSS removes unnecessary semicolons, and HTML collapses inter-tag whitespace.

No. All minification happens entirely in your browser using JavaScript. Your source code never leaves your device, making it safe to use with proprietary or sensitive codebases.
