Frequently asked questions

How do I format HTML?

Paste minified or messy HTML and click Format. Tags are split onto lines and indented so nested structure is easier to scan.

Is this a full DOM / Prettier formatter?

No. It is a lightweight tag-based indenter. Void elements like br and img are handled specially, but attribute reordering and advanced pretty-print rules are out of scope.

Will it fix invalid HTML?

It does not validate or repair markup. Malformed tags may still look odd after indenting — use a browser inspector or validator for serious fixes.

Is my input uploaded?

No. TryDevSnip formats HTML in your browser. Nothing you paste is uploaded to our servers for processing.
