What is an HTML formatter?
An HTML formatter takes messy or minified markup — often a single unindented line pulled from a "view source" or copied from a minified production page — and reformats it with consistent indentation and line breaks so the structure of nested tags becomes easy to read. Pixvert's HTML formatter also works in reverse, minifying formatted HTML down for production use.
HTML that's deeply nested (divs inside divs inside sections) is hard to reason about when it's all on one line or inconsistently indented. Proper formatting makes it immediately clear which closing tag belongs to which opening tag, which is invaluable when debugging layout issues or reviewing markup written by someone else.
This tool is commonly used when inspecting a page's source code, cleaning up HTML exported from a design tool or CMS, or preparing a finished snippet for a code review where readability matters.

When to use an HTML formatter
Debugging page structure

Frequently Asked Questions
Is my HTML sent to a server?
No, all formatting and minifying happens locally in your browser using JavaScript. Your markup is never transmitted or stored.
Will formatting change how my page renders?
No, formatting only adds indentation and line breaks for readability — it doesn't alter the actual DOM structure or how the browser renders it.
What's the difference between formatting and minifying?
Formatting adds indentation and line breaks for readability. Minifying removes unnecessary whitespace to produce the smallest possible output for production.
Does the formatter fix broken or invalid HTML?
It formats the structure it's given but doesn't validate or repair invalid markup — use a dedicated HTML validator if you need to check for syntax errors.
Can I format HTML with embedded CSS and JavaScript?
Yes, `<style>` and `<script>` blocks are preserved as part of the markup structure, though their internal content isn't separately reformatted.
Is there a size limit?
No hard limit is enforced, though very large HTML documents may take a moment to process depending on your device.
