Frequently Asked Questions

Common questions about code minification.

What is code minification?

Minification is the process of removing unnecessary characters (whitespace, comments, newlines) from source code without changing its functionality. This reduces file size, which means faster downloads and better website performance.

Does minification break my code?

No. Our minifier uses a safe-mode approach that only removes unnecessary whitespace and comments. Your code's logic and behaviour remain exactly the same. We also offer an "Aggressive mode" for more compression, but we recommend testing thoroughly if you use it.

How much size reduction can I expect?

Typically:
• HTML: 30-60% reduction
• CSS: 40-70% reduction
• JavaScript: 20-50% reduction

The actual reduction depends on how much whitespace and comments your original code has. When combined with GZIP compression on your server, you can achieve 80-90% total size reduction.

What is the difference between minification and compression?

Minification removes unnecessary characters from the source code itself. GZIP compression (done by your web server) compresses the file for transfer. Both work together — minify your code first, then let your server GZIP it for maximum savings.

Is minified code still readable?

Minified code is harder to read for humans but works the same in browsers. That's why developers keep their original source code for editing and only deploy the minified version to production. Always keep a backup of your original code!

Is my code safe?

Yes, 100% safe. All minification happens entirely in your browser using JavaScript. Your code never leaves your device — no uploads, no server processing, no logging.
