Use the guide alongside the working tool.
Open HTML Formatter →Working input
<main><h1>Hello</h1><p>A clear page.</p></main>Format HTML with a syntax-aware parser and consistent indentation. Uses the bundled Prettier formatter for HTML. Formatting does not execute code, validate business logic or guarantee runtime correctness. Invalid syntax returns an error.
Input and purpose
Format HTML with a syntax-aware parser and consistent indentation.
Start with the working sample, then replace it with your own input. The sample input is: <main><h1>Hello</h1><p>A clear page.</p></main>
Review the result
Uses the bundled Prettier formatter for HTML. Formatting does not execute code, validate business logic or guarantee runtime correctness. Invalid syntax returns an error.
Run processes the current input on your device. Changing an input clears the previous output so you cannot accidentally export stale results.
Copy and export
Copy or download only after reviewing the exact generated text. Nothing is applied to your project or sent to an endpoint.
Use Undo sample to restore your draft. Clear inputs or close the tab when finished; no content is stored in localStorage.
