What is URL Encoding?
URL encoding converts special characters into a format safe for internet transmission. It replaces disallowed characters with % followed by a two-digit hexadecimal code.

The HTTP protocol requires all characters in a URL to belong to the safe ASCII set — everything else must be encoded.
Text→Hello World
Encoded→Hello%20World
Arabic→%D9%85%D8%B1%D8%AD%D8%A8%D8%A7%D9%8B
Encoding Modes
Standard — uses encodeURI() — preserves URL structure characters like / ? # &

Component — uses encodeURIComponent() — encodes everything including / ? # &, ideal for query values.

Base64 — binary-safe encoding using A–Z, a–z, 0–9, +, /. Different purpose from URL encoding.
