Frequently Asked Questions

What is the difference between Encode and Encode Component?

"Encode" preserves URL structure characters like :, /, ?, #. "Encode Component" encodes everything, suitable for individual parameter values.

Can I decode double-encoded URLs?

Yes. Simply click "Decode" multiple times to unwrap each layer of encoding.

Does the URL Parser support all URL formats?

It supports any valid URL that the browser's URL API can parse, including HTTP, HTTPS, FTP, and custom protocols.
