When to encode URLs

Use encodeURIComponent

Encode individual query parameter values, path segments or any part of a URL that might contain special characters like &, =, +, #.

Use encodeURI

Encode a complete URL while preserving its structure. Use when you have a full URL and only need to escape reserved characters.

API & form data

Query strings sent in API calls or HTML forms must be URL-encoded so special characters don't break parsing.

SpaceBecomes %20 (or + in form data)

& and =Encoded in component mode — critical for query params

# and ?Encoded in component mode, preserved in URI mode

Non-ASCIIUnicode chars are UTF-8 encoded then percent-escaped

Base64 Encoder & Decoder
