• Keep code functionality intact while reducing size

FAQs

Will this change my script’s functionality?
No — it only removes formatting and comments. Your logic and behavior remain unchanged.

Can I minify code with ES6+ syntax?
Yes. This tool supports modern JavaScript syntax, including ES6 arrow functions, let/const, etc.

Can I undo the minification?
Not easily — keep a backup of your original code. (A beautifier tool may be added in the future.)

Do you store any of my code?
No — all processing happens locally in your browser. We do not log or save any code.

Is it safe for production use?
Yes. It produces valid, clean JS ready for deployment. Always test your output before going live.

Disclaimer

This tool is provided for performance optimization only. Always test minified scripts in a staging environment before deploying to production. Aivexel is not responsible for script conflicts or functionality errors due to minification.
