About HTML Formatter
Markup that's been minified, copied from a page source, or generated by a template engine usually arrives with no indentation, making nested tags hard to read. The HTML Formatter rewrites it with consistent indentation and line breaks so the document structure, element nesting, and parent-child relationships become clear at a glance.
Paste your HTML and the tool reformats the markup for readability without changing what the page renders. It's free, runs in the browser, and returns clean output instantly with no account needed. Reach for it when you're debugging a layout, learning from a page's source, or tidying machine-generated markup before pasting it into a template or component.

- Make a tangled block of nested divs readable while debugging a layout issue
- Format an HTML email or snippet before pasting it into a component file

FAQ
Does formatting change how the page looks?
No. Browsers ignore the extra whitespace between most tags, so reindenting markup does not affect rendering.
Will it fix broken or unclosed tags?
It reformats based on the markup you give it but is not a validator. Severely broken HTML may not indent cleanly.
Does it preserve inline scripts and styles?
Yes. The content inside script and style tags is kept; the surrounding markup is reindented.
Is whitespace-sensitive content affected?
Content inside elements like pre is meant to preserve whitespace, so review those areas after formatting.
Can I use HTML Formatter on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
