Compress JS for production or beautify for debugging. Remove console.logs, strip comments, and measure exact savings.
Production-ready tools for every JS workflow
Removes comments and unnecessary whitespace while preserving string literals, regex, and template strings safely.
Strip all console.log, console.warn, console.error, and console.info calls from production builds automatically.
Expand minified or obfuscated JavaScript into readable, properly indented code for debugging.
See function count, comment count, console call count, and exact byte savings for your code.

JavaScript minification removes whitespace, comments, and shortens variable names to reduce file size, improving website load speed. Beautification reformats minified or obfuscated JS into readable, indented code for editing or debugging.
Minified JavaScript files load faster because they're smaller. This is a critical optimization step for production websites targeting Core Web Vitals.
Beautify minified JavaScript from websites or libraries to understand how features are implemented or debug unexpected behavior in third-party code.
Strip developer comments and debugging code from your production JavaScript to keep your logic private and reduce file size simultaneously.
For small projects without a build pipeline, use this tool to minify your JavaScript manually before deploying updates to your production server.
JavaScript minification can reduce file sizes by 30–80% depending on comment density and whitespace. Advanced minifiers also mangle variable names (replacing descriptive names with single characters) for additional savings. Combined with GZIP compression and browser caching, minified JavaScript dramatically improves website performance metrics.
