JS Beautifier Tool | Optimize & Compress JS Code

How Our JavaScript Beautifier Tool Works

Step 1: Input Your Code

You can add your JavaScript code in two ways:

• Type or paste code directly into the input box
• Upload a JavaScript file from your computer

Step 2: Choose Formatting Options

Select how you want your code to look:

• Indentation: Choose spaces or tabs (2-8 spaces)
• Brace Style: Select where curly braces should go
• Line Length: Set how long lines should be before wrapping
• Spacing: Control spaces around brackets and operators

Or use quick presets:

• Standard: Normal JavaScript style (default)
• Allman Style: Braces on new lines
• Compact: Less spacing for smaller files

Step 3: Beautify Your Code

Click the "Beautify JavaScript" button. The tool will:

• Clean up your code automatically
• Add proper indentation and spacing
• Fix formatting while keeping your code working
• Show you the formatted result instantly

Step 4: Get Your Formatted Code

After beautification, you can:

• Copy the formatted code to clipboard
• Download it as a new JavaScript file
• Clear everything and start over
