Frequently Asked Questions

Is this tool free?

Yes! The HTML Minifier is completely free with no limits or registration required.

Will minification break my HTML?

Generally no, but the "Collapse whitespace" option may affect content inside <pre> and <textarea> tags. Review the output and test before deploying. The "Remove attribute quotes" option only removes quotes from simple, safe attribute values.

What about JavaScript inside HTML?

JavaScript inside <script> tags is preserved. However, inline JS that relies on specific whitespace patterns (rare) could be affected by whitespace collapse. For production use, always test your minified output.
