Frequently asked questions
Does it change what the page renders?+
No. Beautifying only adds indentation and line breaks between tags; the elements, attributes and their order are preserved, so the browser renders exactly the same result.
Does it reformat the code inside <script> and <style> tags?+
No — that content is printed as-is beneath its surrounding tags rather than re-indented, so JavaScript or CSS syntax is never at risk of being altered.
Does it fix invalid or unclosed tags?+
No. The formatter reindents based on the tags it finds; it doesn’t validate markup or auto-close missing tags.
Is my HTML uploaded anywhere?+
No. Formatting runs entirely in your browser — nothing is sent to a server.
