Input — paste your JavaScript

Output — minified result

Runs 100% in your browser — nothing is uploaded. Plugins like Autoptimize or WP Rocket may already minify site assets; use this for custom snippets, email HTML, or one-off files.

WordPress tip

How to use this on a WP site

Use for small inline scripts or custom JS you enqueue in a child theme — not as a replacement for a full bundler.

This tool does not rename variables (safer for WP snippets).
Prefer wp_enqueue_script with a .min.js file in production.
Test in the browser console after pasting into a snippet plugin.

FAQ

Common questions

Will this break modern JS?

It avoids aggressive transforms. Template literals and strings are preserved. Always test complex modules.

Why no uglify/rename?

Renaming breaks code that relies on global names or WordPress localize objects. Safe minify is intentional.

Is code uploaded?

No — client-side only.
