What is the Code Beautifier?

The Code Beautifier is a free, fast online developer utility that takes messy, unformatted, or minified HTML, CSS, and JavaScript code and transforms it into clean, readable, and well-structured code. Writing code can often result in inconsistent indentation or long strings of text that are difficult to debug or review, especially when collaborating with others or copying snippets from the web. This tool automatically applies standard formatting rules, including proper indentation, line breaks, and spacing, to make your code instantly comprehensible. It is an essential tool for frontend developers, web designers, and anyone working with web technologies.

How to Format HTML, CSS, and JavaScript

Using the Code Beautifier is incredibly simple and efficient:

  1. Select your language: Choose whether you want to format HTML, CSS, or JavaScript using the language selector.
  2. Paste your code: Enter your raw, unformatted code into the input text area.
  3. Format: Click the "Format Code" button. The tool will instantly parse your code and apply the correct formatting rules based on the selected language.
  4. Copy to clipboard: Click the "Copy" button to easily copy the formatted code and paste it into your code editor, IDE, or project files.

100% Secure and Client-Side Processing

We understand that source code often contains proprietary logic, sensitive algorithms, or internal project structures. ToolDojo's Code Beautifier processes everything locally in your browser. Your code is never transmitted over the internet, stored in any database, or saved to any server logs. You can safely format your most confidential source code with complete peace of mind, knowing that the data remains strictly on your own device. We utilize the industry-standard Prettier library running entirely client-side to guarantee both quality and security.
