URL Encoder / Decoder

encodeURIComponent encodes all special characters except A-Z a-z 0-9 - _ . ! ~ * ' ( ). It is used to encode individual URL components like query parameters.

encodeURI encodes a complete URL but preserves special URL characters like / : ? & # = . Use it when you want to encode an entire URL string.

Characters like spaces become %20, accents become percent-encoded sequences, and special characters like ! @ # $ % ^ & * are also encoded.
