Frequently Asked Questions
Why do URLs need encoding?
URLs can only contain a limited character set. Special characters like spaces, &, ?, = and Unicode must be percent-encoded (e.g. space → %20).
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL, preserving characters like / and :. encodeURIComponent encodes individual params, encoding / and : as well.
