About URL Encoding
URL encoding (percent-encoding) replaces unsafe characters with a % followed by their hexadecimal code. For example, a space becomes %20, and & becomes %26.
- Required for special characters in query string parameters
- Characters A-Z, a-z, 0-9, -, _, ., ~ are safe and not encoded
- Use when passing URLs, email addresses, or text with spaces as API parameters
- This tool uses encodeURIComponent, which encodes all special characters except: - _ . ! ~ * ' ( )
