HTML Formatter & Beautifier

Format and beautify HTML instantly — in your browser

Minified HTML is unreadable. Generated markup from CMS platforms, email builders, or template engines often has inconsistent indentation, collapsed tags, and no structure. This free HTML formatter parses the raw HTML and outputs cleanly indented, human-readable code in one click — without installing an extension, creating an account, or uploading anything to a server.

When you need an HTML formatter

Common situations where formatting HTML saves time: reading the source of a competitor's page to understand their structure, debugging a template that renders incorrectly in certain browsers, cleaning up HTML exported from word processors or email marketing tools, reviewing auto-generated markup from a CMS before committing it to source control, and formatting HTML snippets copied from Stack Overflow or documentation sites that lack consistent indentation.

Formatting vs minification — which do you need?

Formatting adds whitespace and indentation to make HTML readable — use this during development, code review, and debugging. Minification removes all unnecessary whitespace to reduce file size — use this before deploying to production. A typical HTML page minifies from 15–40% smaller, which improves page load times and Core Web Vitals scores. This tool supports both directions: beautify for human reading, minify for deployment.

Indentation options

Different teams and style guides prefer different indentation. This formatter supports 2-space indentation (popular in modern JavaScript/CSS ecosystems and frameworks like React and Vue), 4-space indentation (traditional HTML and Python conventions), and tab-based indentation (common in older codebases and some company style guides). Choose the style that matches your project's linting configuration to avoid unnecessary whitespace-only diffs in version control.

Safe for template HTML and CMS content

HTML from CMS editors often includes Twig, Jinja2, Liquid, or Handlebars template tags inside the markup. This formatter treats those as text and does not attempt to parse or validate them, preserving template directives intact. Your HTML is processed entirely in your browser — it is never uploaded to a server.
