Developer guide

HTML formatting helps you inspect markup, templates, CMS output, email snippets, landing page sections, and nested components without rendering untrusted code.

What is an HTML Formatter?

An HTML Formatter turns messy, compressed, or hard-to-read HTML into a structured format with indentation and line breaks.

When should developers use one?

HTML beautify vs HTML minify

Beautify improves readability. Minify reduces whitespace and file size. Formatting does not automatically fix invalid markup.

Formatting should display HTML as code, not execute it. Use sanitization before rendering user-generated HTML in production.
