Key Features of Our Minification Tool

1. Smart Auto-Detection
Our algorithm identifies code type (HTML/CSS/JS) through structural analysis, even in mixed-content files. Manual override available via the dropdown selector.

2. Deep Compression

  • Removes comments, whitespace, and line breaks
  • Preserves important syntax (CSS media queries, JS functions)
  • Optional advanced compression (future update)

3. Enterprise-Grade Security
Unlike cloud-based tools, your code never leaves your browser. We use client-side processing with these safety measures:

// Local processing example
function localMinify(code) {
  // Zero external API calls
  return secureCompression(code);
}

Step-by-Step Usage Guide

Technical Deep Dive: How It Works

Our regex-based engine uses these compression rules:

HTML Minification:

regex

Copy

Download

/<!--.*?-->|\s+/gs → Single-line collapse

CSS Optimization:

regex

Copy

Download

/(\:|\(|\{)\s+|\s+(?=\)|\})/g → Whitespace trimming

JS Compression:

regex

Copy

Download

/(?<!\()\s+([=+\-*/])\s+|\s{2,}/g → Operator cleanup

All patterns are tested against W3C validation standards to prevent broken code.
