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!
