Encode special characters in URLs or decode percent-encoded URL strings. Essential for web developers working with query parameters, API calls, and form data.
URL encoding replaces special characters with percent-encoded equivalents (like %20 for spaces) so they can be safely transmitted in URLs.
URLs can only contain certain ASCII characters. Special characters like spaces, ampersands, and non-ASCII characters must be encoded to be transmitted correctly.
encodeURI encodes a full URI preserving characters like colons and slashes, while encodeURIComponent encodes everything except letters, digits, and a few special characters.
