What does this tool do?
| Direct answer | HTML Beautifier normalizes indentation by tag nesting depth while keeping inline text readable. |
| Key fact | Void elements (br, img, input…) never increase indentation depth because they cannot contain children. |
| Processing | Runs locally in your browser; no data is sent to a server. |
How to use
- Paste HTML into the input.
- Click Beautify HTML.
- Copy the formatted markup.
Example
Input
<div><p>Hello</p><span>world</span></div>
Output
<div> <p>Hello</p> <span>world</span> </div>

Frequently asked questions
Does it change my HTML semantics?
No — only whitespace changes. Tags, attributes, and text are preserved.
What about <pre> content?
Whitespace inside <pre> blocks is preserved; the beautifier does not reformat their content.
Does it handle inline styles and scripts?
Yes — script and style content is left untouched; only the surrounding markup is re-indented.
