What is a Code Beautifier?
A code beautifier (also called a code formatter or code prettifier) is a developer tool that
automatically formats source code according to style conventions. Our professional code beautifier
transforms minified, compressed, or poorly formatted code into clean, well-structured, human-readable
format with proper indentation, spacing, and line breaks. Whether you're debugging minified
JavaScript, cleaning up legacy code, or standardizing code style across your team, our tool
supports 15+ programming languages including JavaScript, TypeScript, Python, HTML, CSS, JSON,
and more.
Features:
- 15+ Language Support: JavaScript, TypeScript, JSON, HTML, CSS/SCSS, XML, YAML, TOML, Python, Go, Rust, GraphQL, Markdown, and SQL
- Customizable Formatting: Choose between 2 or 4 spaces, or use tabs for indentation to match your coding standards
- Dual Functionality: Beautify code for readability or minify it to reduce file size for production deployment
- Instant Processing: Client-side formatting with optional backend enhancement for complex code structures
- 100% Private: All code formatting happens in your browser - your code never leaves your device
- No Installation Required: Works directly in your browser without plugins, extensions, or downloads
- Sample Code Library: Quick-load examples for each language to test formatting capabilities
Common Use Cases:
- Debugging Minified Code: Restore readability to compressed production JavaScript, CSS, or JSON files
- Code Review: Format code before review to ensure consistent style and improve readability
- Learning & Education: Clean up pasted code examples from documentation or tutorials
- Legacy Code Cleanup: Standardize formatting in older codebases with inconsistent styles
- API Response Formatting: Beautify JSON, XML, or YAML responses for easier inspection
- Configuration Files: Format YAML, TOML, or JSON config files for better maintainability
- Production Optimization: Minify code to reduce file size and improve load times
Why Use Our Code Beautifier?
Unlike desktop IDEs or command-line tools, our online code formatter provides instant access
without installation. With support for both beautification and minification, you can format
code for development or optimize it for production. The tool handles syntax edge cases gracefully
and provides clear error messages when input is invalid. All processing happens client-side
for maximum security and privacy—your proprietary code stays on your device. Perfect for developers,
code reviewers, students, and anyone working with source code across multiple programming languages.
