How to Use

This URL Encoder/Decoder helps with web development and URL handling:

🔐 Encoding Features

  • URL Component: Standard percent-encoding for URL parts
  • Full URI: Encode entire URIs while preserving structure
  • Query Parameters: Encode for query string usage
  • Form Encoding: Use + for spaces (application/x-www-form-urlencoded)

🔓 Decoding Features

  • Percent Decoding: Convert %XX sequences back to characters
  • Plus Decoding: Convert + back to spaces
  • Multiple Passes: Handle double-encoded URLs
  • Error Detection: Identify invalid encoding sequences

🔍 URL Analysis

Break down URLs into components:

  • Protocol, hostname, port, path, query parameters, fragment
  • Parameter parsing and formatting
  • Encoding status of each component
  • Validation and error detection

💡 Usage Tips

  • • Use component encoding for individual URL parts
  • • Use form encoding for POST data
  • • Analyze URLs to understand their structure
  • • Enable live processing for real-time results

⚠️ Important Notes

Different encoding methods are appropriate for different contexts. Component encoding is safest for general use, while form encoding is specific to HTML form submissions.

Privacy: All encoding/decoding happens locally in your browser. No URLs are transmitted to any server.
