About URL Encoder
URL encoding (also called percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). It replaces unsafe ASCII characters with a percent sign followed by two hexadecimal digits.
When to Use URL Encoding:
- Query Parameters - When passing special characters in URL query strings
- Form Data - When submitting forms via GET method
- API Requests - When constructing URLs with special characters
- Data Validation - When you need to safely transmit text in URLs
