FAQ
Does this change my HTML structure?
No. It only reformats whitespace and indentation between tags; all elements, attributes and content are preserved exactly.
Is my markup uploaded to a server?
No. Beautifying happens locally in your browser and your HTML is never sent anywhere.
Does it reformat inline script or style blocks?
The contents of script and style tags are left as-is; only the surrounding HTML structure is indented.
