FAQ

HTML beautifier questions

What is an HTML beautifier?

An HTML beautifier formats messy or minified HTML with consistent indentation so tags, text, and nesting are easier to inspect and edit.

Does this HTML beautifier upload my code?

No. Formatting runs in your browser, so pasted HTML stays on your device and is not uploaded to Code Card by this tool.

Can this tool format minified HTML?

Yes. Paste minified HTML and the formatter splits tags across readable lines, indents nested elements, and preserves inline text where appropriate.

Can I remove HTML comments?

Yes. Turn off the comment option to omit HTML comments from the formatted output before copying or downloading.

Why does the formatter show a tag error?

A tag error means the markup has a mismatched or missing closing tag, such as closing a parent element before a child element is closed.
