Frequently asked questions
Does formatting change what the HTML renders as?
No - only whitespace and indentation are added back for readability; the elements, attributes, and content are untouched.
Can it format a full HTML document, not just a fragment?
Yes - it works on anything from a small snippet to a full document with <html>, <head>, and <body>.
Does it validate that the HTML is correct?
No - this reformats structure for readability; it doesn't check for missing tags or invalid nesting the way a dedicated HTML validator would.
Is my HTML sent anywhere?
No - formatting happens entirely in your browser.
