JavaScript Minifier & Beautifier

Compress or format your JavaScript code for production or development.

Why Minify JavaScript?

Minifying JavaScript removes unnecessary characters (whitespace, comments, newlines) to reduce file size. Smaller files load faster, improving page speed and SEO rankings.

When to Beautify JavaScript?

  • Debugging: Unminified code is easier to read and fix.
  • Learning: See the structure of minified libraries.
  • Code Review: Formatted code is easier to compare.

Best Practices

  • Keep source files readable (beautified) in your repo.
  • Minify for production builds automatically via webpack/vite.
  • Combine with GZIP compression for maximum savings.
