What is the JavaScript Minifier and Beautifier?
Smaller JavaScript files load faster and improve your PageSpeed score. The minifier (powered by Terser) removes spaces, comments and shortens variable names safely – usually cutting size by 30–60%. The beautifier does the opposite: it turns minified or messy code into clean, readable, indented JavaScript.
Your code is processed in your browser and never uploaded.
How to use the JavaScript Minifier and Beautifier
- Paste your JavaScript.
- Press Minify or Beautify.
- Copy the result or download it as a .js file.
Tips
- Keep the original source – always edit the readable version, then minify for production.
- Turn off “mangle names” if other scripts call your functions by name.
This JavaScript Minifier and Beautifier is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
