FastMinify - Free Client-Side JS/CSS Minifier

I built FastMinify, a free online tool to minify JavaScript and CSS directly in your browser.

Features:

  • Three compression levels (Conservative/Normal/Aggressive)
  • ES5 to ES2022 compatibility
  • Batch processing for multiple files
  • Unminify, beautify, and JSON tools
  • 100% client-side - your code never leaves your browser

Built with Next.js 15, Terser, and CSSO.

Hope it can be useful for your projects!
