🤔 Why Do You Need a Code Splitter?

Working with large code files can be challenging, especially when you need to share them with AI assistants, upload them to platforms with file size limits, or break them down for easier review and collaboration. Traditional methods of manually copying and pasting code sections are time-consuming and error-prone.

💡 Common Scenarios:
  • Uploading large files to AI platforms like ChatGPT or Claude (which have token/character limits)
  • Breaking down massive legacy code files for team review
  • Splitting documentation or configuration files for easier management
  • Preparing code samples for tutorials or presentations

🚀 How to Use the Code Splitter

Step 1: Input Your Code

You have two options for getting your code into the tool:

  • Upload a File: Click "Choose File" and select any text-based file (.js, .py, .html, .css, .json, etc.)
  • Paste Code: Simply copy and paste your code directly into the text area

Step 2: Choose Split Method

Select the splitting method that best fits your needs:

  • 🧠 Smart Split (Recommended): Automatically detects content type and splits intelligently
  • 📏 By Lines: Splits based on number of lines - great for maintaining code structure
  • 🔤 By Characters: Even character distribution - ideal for size-based limits
  • 📖 By Words: Word-boundary splitting - perfect for text content

Step 3: Set Number of Parts

Choose how many parts you want (2-20). The tool will automatically calculate the optimal size for each part.

Step 4: Split and Copy

Click "Split Code" and your content will be divided into manageable parts. Each part shows character count, line count, and has a one-click copy button.

💡 Pro Tips:
  • For AI platforms, 4-6 parts usually work well for most files
  • Use Smart Split for best results - it preserves code structure and HTML integrity
  • The tool shows real-time stats to help you make the right choice
  • Adjust textarea height using the convenient controls for better viewing

🎯 Smart Splitting Explained

The Smart Split feature is what makes this tool special. Here's how it works:

HTML Content

When splitting HTML, the tool tracks opening and closing tags to ensure no part ends with unclosed tags. It respects the HTML structure and splits at logical boundaries.

Programming Code

For code files, it monitors bracket pairs and tries to split at function or class boundaries rather than in the middle of code blocks.

Text Documents

For regular text, it splits by paragraphs (double line breaks) to maintain readability.

⚠️ Important Note: While Smart Split tries its best to maintain code integrity, always review the split parts before using them, especially for critical code that needs to compile or run correctly.

🔐 Privacy & Security

Your privacy is paramount. This tool:

  • Processes everything locally - No data leaves your browser
  • No server uploads - All splitting happens on your device
  • No data storage - Nothing is saved or tracked
  • No registration required - Use it instantly without any signup

💻 Browser Compatibility
