About the JavaScript Minifier

Minify and mangle your JavaScript with Terser — the same engine used by modern build tools. Code is processed server-side in memory, never stored, and you get an immediate size report. Minified scripts load faster and are harder to casually read.

How to use it

  1. Paste your JavaScript into the left editor.
  2. Press Minify — Terser compresses and mangles it.
  3. Copy the output, or check the savings percentage first.

Frequently asked questions

What does 'mangle' mean?

Terser renames local variables to short names and removes dead code, which shrinks the file significantly. Always test minified code before shipping it.

Is my code stored?

No. It is processed in memory and discarded. Nothing is written to disk.
