HTML Formatter
Free HTML formatter online - indent and pretty-print messy or minified HTML snippets in your browser.
About the HTML Formatter
This free HTML formatter indents and structures markup so nested tags are easier to read, review, and debug. One-line HTML from a CMS export or minified template is hard to edit safely; formatting restores hierarchy without changing the meaning of the markup.
Paste HTML, run the formatter, scan the indented output, then copy the readable result back into your editor. It is a best-effort beautifier for everyday snippets - not a full browser HTML5 conformance suite.
When to format HTML
- Cleaning exports before editing modules or email templates
- Reviewing nested lists, tables, and component markup
- Preparing a snippet for a code review or documentation page
- Spotting unclosed tags that disappear inside a single long line
How to use
- Paste your HTML into the input field.
- Run the formatter and scan the indented output.
- Fix structural issues you notice (missing closers, accidental nesting).
- Copy the result into your project or CMS.
Tips
- Keep
<script>and<style>blocks intact; review them if the template is sensitive. - If whitespace inside
<pre>or text nodes matters, verify those areas after beautifying. - Use the HTML Minifier when you are ready to ship a compact production version.
- Formatting does not replace a validator - broken tags still need a manual fix.
FAQ
Will formatting fix invalid HTML? It improves readability. Broken tags still need a manual fix or a validator.
Is this the same as Prettier? No - this is a lightweight online formatter for quick paste workflows.
Does it change tag order? The goal is indentation and structure for reading, not a full DOM rewrite of your document.
