Code Beautifier & Formatter

A code beautifier (also known as code formatter or pretty printer) is an essential tool for web developers that transforms messy, minified, or poorly formatted code into clean, readable, and properly indented code. Our tool supports HTML, CSS, JavaScript, and JSON formatting.

Why Beautify Code?

• Readability: Make code easier to read and understand
• Debugging: Identify issues faster with properly formatted code
• Maintenance: Simplify code updates and modifications
• Collaboration: Ensure consistent code style across teams
• Learning: Study minified code from production sites
• Code Review: Review code more effectively with proper formatting

Beautify vs Minify

How to Use

1. Select your code language (HTML, CSS, JavaScript, or JSON)
2. Paste your code into the input area or upload a file
3. Choose your preferred indentation size (2, 4, or 8 spaces)
4. Click "Beautify" to format or "Minify" to compress
5. Copy the output or download as a file

Best Practices

• Use consistent indentation across your project (2 or 4 spaces)
• Beautify code before committing to version control
• Use minified code only for production deployment
• Keep source maps when minifying for debugging
• Automate formatting with build tools (Prettier, ESLint)
• Review beautified code before making changes
