HTML Beautifier & Minifier

The HTML beautifier re-indents HTML source: it indents tags, breaks long attribute lines, and aligns children so minified or inconsistent markup becomes readable. You can also minify — collapse HTML to a single line for production.

Common scenarios: reading legacy HTML with no indentation, cleaning up markup pasted from rich text editors, tidying email templates, unifying style during PR review, and turning "View Source" output into something usable.

No. Only whitespace, indentation, and line breaks change — tags and attributes are never added or removed. Whitespace-sensitive tags like <pre> and <textarea> keep their inner content intact so styling is preserved.

Look for self-closing mistakes (<br> vs <br/>), unclosed tags, or inline scripts containing <. Non-strict HTML can produce parsing drift. For template languages (Vue, JSX, Handlebars) use a dedicated formatter — HTML Beautifier does not guarantee template-syntax fidelity.

No, everything runs locally. Admin-portal HTML and internal email templates are safe to paste.

DevTools only pretty-prints in the debug panel and the result disappears on reload. The HTML Beautifier emits source you can copy back into a file, commit to a PR, or share with teammates — with batch processing and configurable indentation.
