Paste an HTML fragment into the input, select two spaces, four spaces, or tabs, and press Beautify. Compare the output with the original before copying or downloading it. The example below uses an attribute that the bounded formatter can place on its own line without changing the attribute value. Keep your source file separately so you can compare behavior after applying a formatting change to a real page.
This implementation deliberately preserves documents containing whitespace sensitive or embedded language elements such as pre, textarea, script, and style. An unchanged result can therefore be the correct outcome rather than a failed action. It does not repair invalid markup or validate your whole website. Test the resulting page in its normal environment, especially when text nodes or inline elements rely on exact whitespace.
Input: <div class="box"></div>
Beautify output:
<div
class="box"></div>
Processing runs in your browser. Choosing Share uploads the selected tool state; anyone with the link can open it. Signing in to save sends content to your account library and records save history. Review the selection before either action. Closing the page does not delete those copies. Copying locally does not create a server share.
It accepts HTML text and applies bounded spacing changes to markup it can scan safely. Embedded languages, whitespace sensitive elements, and declarations can cause the original to be preserved. Do not treat acceptance as complete HTML validation or automatic repair. Compare the output with your source and test it in the consuming page.
Processing happens in browser memory, so the practical size depends on your device and document structure. No fixed execution time or unlimited-memory guarantee applies. Start with a representative fragment when a document is unwieldy. The page does not stream a large website through a server or inspect external stylesheets and scripts.
The bounded scanner deliberately preserves documents containing script, style, pre, textarea, and other whitespace sensitive elements. It also preserves constructs it cannot rewrite safely. A preservation notice means the original source was retained. This is not a full HTML parser or repair service; use your project tooling when broader formatting is required.
No. It avoids rewriting embedded languages as HTML. Use the corresponding formatter on separate source if you need to inspect CSS or JavaScript. Keep the original document and run your normal application checks afterward, particularly where inline text, attribute values, or significant whitespace must survive a transformation unchanged.
