HTML Formatter / Beautifier
Beautify and indent messy HTML code into clean, readable format instantly.
What Is an HTML Formatter?
An HTML Formatter (also called an HTML Beautifier) is a tool that takes poorly structured, minified, or hard-to-read HTML code and reorganizes it with consistent indentation, proper line breaks, and logical nesting. Whether you're working with legacy code, minified production files, or copy-pasted snippets, a formatter instantly transforms your markup into clean, human-readable code — saving time and reducing errors.
How to Use This Tool
Simply paste your raw or messy HTML into the Input panel on the left. Choose your preferred
indent style (2 spaces, 4 spaces, or tabs) and toggle options like attribute wrapping or comment preservation.
Click Beautify HTML to instantly see formatted output in the right panel. Use the
Copy Output button to copy to clipboard, or Download to save as an
.html file. You can also Minify the output to compact it back down for
production use.
Common Use Cases
HTML formatting is essential for many workflows: debugging complex nested layouts, onboarding on existing codebases, preparing code for code reviews or documentation, cleaning up email templates, making CMS-generated markup readable, and undoing minification from production builds. Developers, designers, content editors, and QA engineers all benefit from having clean, consistently indented HTML that's easy to scan and modify.
Frequently Asked Questions
Does the formatter change the behavior of my HTML?
No. The formatter only adjusts whitespace (spaces, tabs, and newlines) between tags and content. It does not alter tag names, attributes, content text, or the document structure in any way that would affect how browsers render your page.
Will HTML comments be kept after formatting?
Yes, by default the "Preserve Comments" option is enabled, so all <!-- ... --> comments are kept intact and properly indented. You can uncheck this option if you want comments stripped from the output.
What does "Wrap Attributes" do?
When enabled, each HTML attribute is placed on its own line when a tag has multiple attributes. This is especially helpful for tags with many attributes (like form inputs or SVG elements) making them much easier to read and diff.
What is "Collapse Empty Tags"?
When this option is enabled, tags with no content like <div></div> are collapsed onto a single line instead of spreading across multiple lines. This keeps the output more compact for elements that have no children.
Can I use this tool to minify HTML?
Yes! After formatting, click the Minify button to compress the output by removing all unnecessary whitespace. This is handy for converting a beautified version back to a production-ready minified format.
Is my HTML code stored or sent anywhere?
No. All processing happens entirely in your browser using JavaScript. Your HTML code never leaves your device and is not stored, logged, or transmitted to any server. It's 100% private and secure.
