HTML Beautifier

Clean Up Messy HTML Instantly

Working with minified or disorganized HTML can be a nightmare. Our HTML Beautifier (also known as a pretty printer) solves this by taking raw, jumbled code and transforming it into a structured, easy-to-read format. Whether you are debugging legacy code, learning web development, or collaborating with a team, ensuring your HTML is properly indented is critical for maintainability.

This tool runs entirely in your browser, ensuring maximum privacy. Your code is never sent to a server, making it safe for confidential projects. With support for custom indentation (2 spaces, 4 spaces, or tabs), you can enforce your preferred coding standards instantly.

Frequently Asked Questions

What is an HTML beautifier?

An HTML beautifier is a developer utility that parses unformatted or minified HTML strings and applies consistent indentation, line breaks, and nesting rules. This process restores the visual structure of the code, making it human-readable.

How do you beautify HTML code?

Simply paste your code into our tool above, select your indentation preference (spaces or tabs), and click "Beautify HTML." The tool will automatically restructure the tags and content for optimal readability.

Why is it important to format HTML code?

Proper formatting allows developers to visually understand the hierarchy of the document. It makes spotting syntax errors—like unclosed tags or improper nesting—significantly faster and ensures the codebase remains clean for future updates.

Can an HTML beautifier fix broken HTML?

While it cannot auto-correct invalid syntax or missing brackets, a beautifier organizes the structure so that these errors become glaringly obvious. It is an excellent first step in the debugging process before running code through a validator.
