What is a JavaScript Beautifier? 🤔
A JavaScript Beautifier, also known as a JS Formatter or Prettifier, is a tool designed to take messy, unformatted, or minified JavaScript code and transform it into a well-structured, readable, and aesthetically pleasing format. It automatically applies consistent indentation, spacing, line breaks, and brace styling, making the code significantly easier for developers to read, understand, and debug. This is essential for maintaining code quality, especially in collaborative projects.

Key Features of Our JavaScript Beautifier Suite 🌟
We've packed our tool with features to make it the best online javascript beautifier available.
General JavaScript Beautifiers
This is the core of our tool. It provides standard formatting options that are widely accepted in the developer community. You can customize indent size (spaces or tabs), brace style, and more to fit your personal or team's coding standards.
Browser Extension Simulation
For those who love the convenience of browser tools, our interface is designed to be as fast and accessible as a javascript beautifier chrome extension. With quick copy-paste actions and instant results, you get the extension experience without needing to install anything.
Powerful Deobfuscation
Minified code is great for production performance but a nightmare for debugging. Our javascript beautifier deobfuscator mode expands compacted code, adds line breaks, and standardizes variable declarations, making inscrutable one-liners readable again.
Integrated HTML and JavaScript Beautifying
Modern web pages are a mix of HTML and JavaScript. Our tool is a comprehensive html and javascript beautifier. It correctly identifies and formats JavaScript inside tags without breaking your HTML structure, a common issue with simpler formatters.
Editor-Specific Presets (VSCode, Sublime, Atom)
Maintain consistency across your development workflow. If you use Visual Studio Code, you can select our vscode javascript beautifier preset. The same goes for fans of Sublime Text or Atom. These presets automatically apply the default formatting rules of those popular editors.
- javascript beautifier vscode: Applies common Prettier-like settings with 2-space indentation.
- javascript beautifier sublime: Configured for the typical 4-space indentation preferred by many Sublime Text users.
- atom javascript beautifier: Sets up formatting that aligns with Atom's out-of-the-box behavior.
