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.
