Minify and compress JavaScript code. Remove comments, whitespace, and reduce file size instantly.
Minification reduces JavaScript file size by removing unnecessary characters — comments, whitespace, newlines, and formatting — without changing functionality. This results in:
Faster page loads: Smaller files download faster, improving Core Web Vitals and user experience.
Lower bandwidth costs: Reduced data transfer for both server and users.
Better SEO: Page speed is a Google ranking factor. Minified JS helps improve scores.
For production builds, combine minification with gzip/brotli compression and tree-shaking for maximum savings.
This tool runs entirely in your browser — no code is sent to any server. It removes single-line (//) and multi-line (/* */) comments, collapses whitespace, and strips unnecessary newlines while preserving string literals and regex patterns.
For production use, consider tools like terser, esbuild, or swc which also perform variable renaming, dead code elimination, and tree shaking.
