Boost Your Site Speed with Our JavaScript Minifier

JavaScript is essential for modern, interactive websites, but large script files can drastically slow down page load times. Our JS Minifier tackles this problem by compressing your JavaScript code into its most compact form. By removing unnecessary characters and shortening variable names, it reduces the overall file size, leading to faster downloads, quicker parsing, and a better experience for your users.

How It Works

This tool leverages the power of two industry-standard libraries: Terser.js for minification and JS-Beautify for formatting. When you minify, Terser analyzes your code, removes whitespace and comments, shortens variable names, and performs other advanced optimizations to create the smallest possible file. When you format, JS-Beautify tidies up messy code into a clean, readable structure.

Key Features

  • Advanced Minification with Terser: Goes beyond simple whitespace removal to intelligently shorten variable names and optimize code structure for maximum compression.
  • Code Formatting (Beautifier): Clean up and reformat unreadable or minified JavaScript back into a well-structured, indented format for easy debugging.
  • Real-time Compression Stats: Instantly see the original size, the new compressed size, and the total savings percentage to understand the impact of minification.
  • Error Handling: If your JavaScript contains a syntax error, the tool will report the error message from Terser, including the line and column number, to help you debug.
  • User-Friendly Interface: Simple controls for pasting, clearing, and copying code make the entire process quick and intuitive.
  • Client-Side Security: Your code is processed entirely within your browser and is never sent to any external servers, ensuring your work remains private.
