JavaScript Minifier & Compressor

Quickly strip comments and compress JS for smaller files. (Client-side, best-effort.)

Minify & Compress JS

Paste your JavaScript below:

Remove comments

Collapse whitespace

Warning: This is a simple client-side minifier — it may break complex JS (strings, regex). For production use Terser/Uglify.

A JavaScript minifier reduces file size by removing comments, line breaks and unnecessary spaces. This improves load time and performance.
