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.
