Developer guide
Format HTML for cleaner debugging and reviews
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?
Use it when debugging minified HTML, reviewing copied snippets, cleaning CMS output, inspecting email templates, or preparing examples for documentation.
HTML beautify vs HTML minify
Beautify improves readability. Minify reduces whitespace and file size. Formatting does not automatically fix invalid markup.
HTML formatting and security
Formatting should display HTML as code, not execute it. Use sanitization before rendering user-generated HTML in production.
