How to Use JavaScript Minifier

The JavaScript Minifier is a free online tool that reduces JavaScript file size by removing comments and extra whitespace. While it performs basic minification (not full uglification with variable renaming), it effectively reduces file size for simpler scripts and quick optimization needs. The tool shows a comparison between original and minified character counts with percentage saved. Use it for quick JS optimization, preparing scripts for inline embedding, or reducing bundle size for simple projects. All processing runs in your browser with no code sent to external servers, keeping your source code private.

Step-by-Step Instructions

  1. Paste your JavaScript code into the input area
  2. Click the minify button
  3. View the minified output with size comparison
  4. Copy the minified JavaScript code
