HTML Formatter
This HTML formatter beautifies and minifies markup with js-beautify-powered indentation controls - indent size, optional line wrapping, and newline preservation. Paste a single-line template or messy export and get readable HTML in one click.
Everything runs client-side for speed and privacy. Frontend developers use it to re-indent components before code review; learners use it to see tag structure clearly. For deep style-only customization workflows, keep Options open and tune wrap length to match your team’s style guide.

Frequently Asked Questions
Is this the same as an HTML validator?
No. This page focuses on format and minify. Structural linting is a separate concern - use a dedicated HTML validator when you need rule-based checks.
Will scripts in my HTML execute?
The editor displays source only. We do not inject your HTML into the parent page as live DOM with scripts enabled.
Can I control wrap length?
Yes. Set wrap line length in Options for attribute-heavy tags, or leave 0 to disable wrapping.
Does minify break inline JavaScript?
Minify collapses inter-tag whitespace. Keep critical spacing inside <pre> or text nodes in mind before shipping minified markup.
