HTML Formatter
Prettify or minify HTML with configurable indentation and syntax-highlighted output. Paste messy or minified markup and get properly indented, readable code in one click. Works entirely in your browser — nothing is sent to any server.
Tips
- Indentation reveals nesting errors — mismatched or unclosed tags become visually obvious in a formatted tree.
- Formatting does not change how the browser renders the page — whitespace between elements is collapsed.
- Use this before committing HTML to version control for cleaner diffs.
- For production, minify HTML to reduce download size — formatting is for readability, not deployment.
