URL Encoder / Decoder

Encode or decode a URL component safely.

Encode a query value

The text “a b&c” becomes a%20b%26c. The ampersand is encoded so it can be part of a query value rather than separating parameters.

When to use it

Encode individual values before building a query string. Decoding a malformed percent escape produces an error.
