Frequently Asked Questions
An HTML formatter (also called an HTML beautifier) takes compressed, minified, or unreadable HTML and reformats it with consistent indentation and line breaks making it easy to read, debug, and edit. You need one when debugging minified template output, inspecting page source copied from DevTools, cleaning up CMS-generated or framework-rendered HTML, or reading markup that was written without any formatting. Our tool handles all of these in one click, paste your HTML, hit Format, and get clean, indented markup ready to work with.
Paste your minified or collapsed HTML into the editor and click 'Format HTML'. The tool parses every tag, calculates the correct nesting depth, and applies 2-space indentation to each element, all in under a second. Inline elements like <strong> and <a> stay on the same line as their surrounding text, and self-closing tags like <img> and <meta> are handled correctly without double-indenting. Click 'Insert Sample' to see an instant before-and-after with a full minified HTML document if you want to test it first.
Simple regex-based formatters break on real-world HTML because they can't distinguish inline tags from block elements. Wrapping <strong> onto its own line produces broken, unreadable markup. Our formatter uses a token-based parser that correctly classifies every element, inline tags like <span>, <em>, <code>, and <a> stay attached to their text, block elements get their own indented line, and self-closing void elements like <img> and <br> are never incorrectly indented. The result is formatted HTML that looks exactly like a developer wrote it by hand.
Yes, the formatter works on any valid HTML input, from a single <div> block to a complete <!DOCTYPE html> document. You don't need to include <html>, <head>, or <body> tags. Just paste whatever HTML you have a component snippet, a template partial, a copied <section>, or a full page and the formatter handles it correctly. This makes it equally useful for React/Vue/Angular template debugging, email HTML formatting, CMS block output, and full-page source inspection.
Our formatter processes standard HTML syntax, it correctly handles any HTML that a browser can parse, including the output of template engines after they've rendered their variables. If your Jinja, Twig, Handlebars, or Blade template has already been rendered to plain HTML (for example, copied from browser DevTools or a server response), it will format perfectly. For unrendered template source files containing {{ variables }} or {% blocks %}, the formatter will pass through the template syntax untouched and still indent the surrounding HTML structure correctly in most cases.
