Frequently Asked Questions

Minification removes unnecessary characters from source code — whitespace, comments, line breaks, and optional syntax — without changing functionality. This reduces file size for faster page loads.

This tool supports HTML, CSS, and JavaScript minification. Each language has tailored rules: HTML removes comments and collapses tag whitespace, CSS strips comments and unnecessary spaces, JS removes comments while preserving strings.

Typical compression ranges from 10% to 60% depending on how much whitespace and comments your code contains. The tool shows before/after sizes and compression percentage.

Yes. All minification happens locally in your browser — no code is sent to any server.
