Frequently Asked Questions
What does minification do?
Minification removes unnecessary whitespace, line breaks, and optionally comments and console.log statements to reduce file size while preserving functionality.
Can I also beautify code?
Yes. The beautify mode reformats minified JavaScript with proper indentation and line breaks, making it readable and easier to debug.
Does it remove console.log statements?
Yes, optionally. Enable the "Strip console.log" option to remove all console.log, console.warn, console.error, and similar debugging statements.
What are the use cases?
Reducing JavaScript file sizes for faster page loads, cleaning up code for production, debugging minified vendor scripts, and removing debug statements before deployment.
Is my code kept private?
Absolutely. All processing happens locally in your browser. No JavaScript code is ever sent to any external server — perfect for proprietary code.
