How this HTML formatter helps

Before and after formatting

Paste compact, copied, or hard-to-read HTML into the input pane. FormatPaste cleans common paste artifacts first, then formats the code into readable output that is easier to scan, debug, share, or copy into your editor.

Common HTML formatting use cases

Use it for quick snippets from documentation, AI chat output, Stack Overflow answers, config examples, API responses, old files, minified blocks, and code that picked up line numbers or markdown fences while being copied.

Safe paste reminder

FormatPaste is built for speed, but you should avoid pasting passwords, API keys, tokens, private keys, recovery codes, customer data, or other secrets into any online formatter. Use local tools for sensitive code.

HTML formatting example

Before

<div class="card"><h2>Pricing</h2><ul><li>Free</li><li>Pro <strong>$9</strong></li></ul><a href="/signup" class="btn">Start</a></div>

After

<div class="card">
  <h2>Pricing</h2>
  <ul>
    <li>Free</li>
    <li>Pro <strong>$9</strong></li>
  </ul>
  <a href="/signup" class="btn">Start</a>
</div>

When to use a HTML formatter

Beautify minified or generated HTML

Page builders, CMS exports, email tools, and View Source often produce HTML on one long line. Formatting indents every nested element so you can see the structure of the page and find the part you need to edit.

Clean up copied components

Markup copied from DevTools, component libraries, or AI chat answers often has uneven indentation. Paste it here to get consistent nesting before you drop it into a template or a pull request.

Spot nesting mistakes

When every child element is indented under its parent, a list item outside its list, a div closed too early, or a form field in the wrong container becomes obvious at a glance.

Format HTML email templates

Email HTML is usually deeply nested tables with inline styles. Formatting makes those tables readable so you can change copy, links, or spacing without breaking the layout.

HTML Formatter FAQ

How do I format HTML online?

Paste HTML into the input pane and the formatter creates readable output.

Can it format nested HTML?

Yes. It formats nested markup into a more readable structure.

Is this HTML formatter free?

Yes. It is free to use.

Does formatting change how my HTML renders?

The formatter is whitespace-aware: it adds indentation and line breaks between block elements while keeping inline elements such as span, a, and strong intact, so the page renders the same.

Can it format HTML with inline CSS and JavaScript?

Yes. Style and script blocks inside the HTML are formatted with the matching CSS and JavaScript rules, so a full page snippet comes back consistently indented.

What indentation does the HTML formatter use?

Nested elements are indented with two spaces, and long attribute lists are wrapped onto separate lines so each attribute is easy to read.

Can it fix broken HTML?

It can format valid markup but will not guess where missing closing tags belong. If tags are badly unbalanced, fix the structure first and then format.
