Can this format a full HTML document?
Yes. You can paste a full HTML document or a smaller snippet. The formatter is designed for common markup cleanup.
Does it validate HTML?
It does not perform standards validation. It formats and minifies text. Use a validator for strict HTML correctness checks.
Is my HTML uploaded?
No. Formatting runs locally in your browser.
Can this format JSX or framework templates?
It is intended for HTML snippets. Some JSX or template syntax may format acceptably, but framework-specific code should be checked with the formatter used by that framework.
When should I minify HTML?
Minify only when compact output matters, such as short embeds or production delivery. Keep readable HTML while reviewing, documenting, or debugging markup.
