About JavaScript Minifier

This tool helps you minify your JavaScript code by removing unnecessary characters like:

  • Whitespace (spaces, tabs, newlines)
  • Comments (single-line and multi-line)
  • Unnecessary semicolons

Minifying your JavaScript can significantly reduce file size, leading to faster page load times and improved website performance.
