📖 About URL Encoding
🔧 What is URL Encoding?
URL encoding (also called percent-encoding) converts special characters into a format that can be safely transmitted in a URL. Characters like spaces, symbols, and non-ASCII text are replaced with % followed by their hexadecimal value.
🎯 When to Use It
- Query string parameters with spaces or symbols
- File paths with special characters
- Form data submitted via GET requests
- API calls with user-generated content
💡 encodeURIComponent vs encodeURI
This tool uses encodeURIComponent(), which encodes all special characters. Use encodeURI() when you want to preserve URL structure characters like /, ?, and &.
