HTML Formatter / Beautifier

What is an HTML Formatter?

An HTML formatter, or beautifier, takes minified or inconsistently indented HTML and reformats it with clean indentation, sensible line breaks, and proper nesting so the document is easy to read and edit. HTML delivered to the browser is frequently minified for performance, which makes it almost impossible to scan or debug by hand.

Our HTML Formatter uses a proven beautification engine that understands HTML's quirks — void elements like img and br that never close, inline versus block elements, and embedded script and style blocks — to produce output that reflects the true structure of your document.

How to Beautify HTML

• Paste your HTML, or click Sample to load an example fragment
• Choose 2 spaces, 4 spaces, or tabs for indentation
• The formatted, nested markup appears instantly in the output pane
• Embedded CSS and JavaScript inside style and script tags are kept intact
• Click Copy to copy the clean HTML to your clipboard

Why Format Your HTML?

Well-indented HTML makes structure obvious: you can immediately see which elements are nested inside which, spot unclosed tags, and locate the section you need to edit. This dramatically speeds up debugging layout issues and modifying templates.

Developers format HTML when inspecting page source, cleaning up output from CMS platforms and page builders, preparing email templates, and reviewing markup generated by frameworks. Clean HTML is also easier to diff in version control, making code reviews faster and clearer.

Privacy

All beautification happens in your browser. Your HTML — which may contain unreleased markup, internal URLs, or proprietary templates — is never sent to a server, so the tool is safe for confidential work.
