Frequently Asked Questions

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URL, preserving characters like :, /, ?, &, =. encodeURIComponent encodes a URL component (like a query value), encoding everything including :, /, ?, & and =. Our tool uses encodeURIComponent logic.

Why does %20 appear in my URL?

%20 is the percent-encoded form of a space character. URLs cannot contain literal spaces, so browsers automatically encode them.
