Frequently Asked Questions
What is URL encoding?
URL encoding (percent-encoding) replaces unsafe ASCII characters with a % sign followed by two hexadecimal digits. For example, a space becomes %20.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL preserving protocol and domain structure. encodeURIComponent encodes individual components like query parameters, encoding more characters.
Why do URLs need encoding?
URLs can only contain certain ASCII characters. Special characters like spaces, ampersands, and non-ASCII text must be encoded to be transmitted correctly.
