Frequently Asked Questions

Why do URLs need encoding?

URLs can only contain certain characters. Special characters like spaces, &, and # must be encoded to be safely transmitted in URLs.

What characters are encoded?

Characters outside the safe set (A-Z a-z 0-9 - _ . ~) are percent-encoded. For example, space becomes %20.

Is the encoding done on my device?

Yes. All encoding and decoding happens in your browser without sending data to any server.

Can I encode full URLs?

Yes, but be careful to only encode the parts that need encoding. The protocol (https://) and domain should not be encoded.
