Frequently asked questions
Does minifying HTML change how the page looks?
It should not. Only comments and extra whitespace are removed, and pre, textarea, script and style are left untouched, since spacing matters there.
Is my code uploaded to a server?
No. Formatting happens entirely in your browser, so you can use it with private code.
Does it fix errors in my HTML?
It is not a validator: it formats the code as it is. If a tag is not closed, the result will show that same problem.
How is this different from the XML formatter?
HTML tolerates tags without a closing tag, like br or img, while XML requires every tag to be closed. For strict XML documents, use the XML formatter.
