URL Encoding Quick Reference

encodeURI vs encodeURIComponent

encodeURI — Encodes a full URL but preserves special URL characters (: / ? # @ & = + $)

encodeURIComponent — Encodes everything except A-Z a-z 0-9 - _ . ! ~ * ' ( )

Rule of thumb:

Use encodeURIComponent for query parameter values

Use encodeURI for full URLs

Common Encodings

space → %20 or +

& → %26

= → %3D

? → %3F

# → %23

/ → %2F

@ → %40

RFC 3986 Characters

Unreserved (never encoded):

A-Z a-z 0-9 - _ . ~

Reserved (have special meaning):

: / ? # [ ] @ ! $ & ' ( ) * + , ; =

Reserved characters should only be encoded when used outside their special purpose.
