Frequently Asked Questions
What does an HTML formatter do?
It takes compressed or poorly indented HTML and reformats it with consistent indentation and line breaks so the nesting of elements, attributes, and structure is easy to read.
Does it validate HTML too?
The formatter focuses on readability. It may surface obvious structural issues but is not a full HTML validator — use a dedicated validator if you need spec-level conformance checking.
Will it change my HTML content or attributes?
The formatter should only change whitespace and indentation. Review the output to confirm no content changes occurred before using the result in production templates or code.
Is my HTML uploaded to be formatted?
No. Formatting runs in your browser. Avoid pasting HTML that contains API keys, auth tokens, or sensitive user data.
