What is URL Encoding?

URL encoding (percent-encoding) replaces unsafe characters in URLs with a % followed by two hexadecimal digits. For example, a space becomes %20, and & becomes %26. This ensures URLs are transmitted correctly across the internet.

encodeURI vs encodeURIComponent

Encode (encodeURI): Encodes a full URI, preserving characters like :, /, ?, #
Encode Component: Encodes everything including reserved URI characters — use for query parameter values
Decode: Reverses both encoding types automatically
