FAQ

Is minified HTML still valid?

Yes! Minified HTML is functionally identical to the original. Only unnecessary whitespace and comments are removed — all tags, attributes, and content remain intact.

Does minification break my page layout?

No, HTML minification is safe. It only removes whitespace, comments, and redundant syntax. Your page will render exactly the same in the browser.

How much size reduction can I expect?

Typically 10–30% reduction depending on how much whitespace and comments your HTML contains. Well-commented or indented HTML can see even higher savings.

Can I undo minification?

Use our HTML Formatter to beautify minified HTML back into a readable format with proper indentation.

Is my HTML data sent to a server?

No. All processing happens in your browser. Your HTML code never leaves your device, ensuring complete privacy.
