Frequently asked questions
Does it preserve <pre>, <script> and <style> content?
Yes. Content inside pre, script, style and textarea is treated as raw text and is not re-indented or collapsed, so code blocks stay intact.
What does Minify remove?
All HTML comments and unnecessary whitespace between tags. A single space is preserved between text and inline tags so spacing in rendered output is unchanged.
Does it fix invalid HTML?
No. The formatter respects the structure you give it. If your HTML is invalid (unclosed tags etc.) the output may also be invalid — fix the markup first.
Is my HTML uploaded?
No. Formatting and minifying happen entirely in your browser.
