What is URL Encoding?
URL encoding (also called percent-encoding) converts characters into a format that can be transmitted over the Internet. URLs can only contain certain characters from the ASCII set. Any character outside this set must be encoded.
Why URL Encoding Matters
- Special Characters: Spaces, ampersands, and other special characters must be encoded
- Data Integrity: Ensures data is transmitted correctly without corruption
- Security: Prevents injection attacks and URL manipulation
- Compatibility: Ensures URLs work across all browsers and systems
