HTML Formatter & Beautifier
Format and beautify HTML online. Indent, wrap, and clean up minified or messy HTML in your browser.
About HTML Formatting
Minified HTML — everything on one line, no indentation — is fine for production but painful to read. The HTML Formatter expands minified or unstructured markup into a clean, indented version where the document tree is visually obvious. It only touches whitespace between tags; attributes, text content, and the meaning of the page are unchanged.
How to use
Paste your HTML and press Format. Choose 2 or 4 spaces of indentation to
match your codebase. Inline <script> and <style> blocks
are kept as-is and indented to align with their parent element; their contents are not
reformatted (use a JavaScript or CSS formatter for those).
Privacy
All formatting runs in your browser using the js-beautify library. Your HTML never leaves this page.
