About This Tool
Minified or automatically generated HTML is fast to deliver but nearly impossible to read or debug. This tool takes any HTML input — no matter how compressed or inconsistently indented — and reformats it into clean, human-readable code.
The formatter runs entirely in your browser, so your code never leaves your device. That makes it a safe choice for working with proprietary templates, internal dashboards, email HTML, or any markup you would rather not share with an external service.

Common Questions
Does my HTML code get sent to a server?
No. The HTML Beautifier runs entirely in your browser using JavaScript. Your code is never uploaded or transmitted anywhere.
Will it format inline <script> and <style> blocks?
The tool preserves the content of <script>, <style>, and <pre> blocks as-is. JavaScript and CSS have their own formatting rules that fall outside the scope of an HTML formatter.
Can it handle minified HTML?
Yes. The formatter is specifically designed to work with minified HTML — it tokenizes tags correctly even when everything is on a single line with no whitespace.
