FAQ

What formatting rules are applied?: Tags are indented, attributes stay on the same line, and content is separated for readability. You can choose 2 or 4 space indentation. The output is HTML source — not rendered in the page.
Round-trip with the HTML Minifier?: Yes — minify with the HTML Minifier and beautify back here. The two tools are designed to work together.
Is my HTML uploaded anywhere?: No. All formatting happens locally in your browser.
