ℹ️ About URL Encoding

What is URL Encoding?

URLs can only contain a limited set of ASCII characters. Special characters (spaces, &, ?, #, etc.) must be percent-encoded — replaced with %XX where XX is the hex code.

encodeURI vs encodeURIComponent

🔗 encodeURI — encodes a complete URL. Preserves : / ? # [ ] @ ! $ & ' ( ) * + , ; =

🔌 encodeURIComponent — encodes a single component (query param value). Encodes almost everything except - _ . ! ~ * ' ( )

Common Encodings

space → %20
& → %26
= → %3D
? → %3F
# → %23
+ → %2B
/ → %2F
