FAQ
How do I beautify HTML online?
Paste your HTML into the input, click Format, and get properly indented markup. Each nested element is indented by 2 spaces, making the structure immediately clear.
Why is my HTML minified?
Build tools like webpack, Vite, and Next.js minify HTML for production to reduce file size. This formatter reverses that process so you can read and inspect the output.
Does the formatter fix broken HTML?
It reformats existing HTML. It won't add missing closing tags, but it will make structural errors more visible so you can fix them manually.
