Encoding transforms data from one format into another representation, such as converting text to Base64 or URL-safe characters, so it can be safely transmitted or stored.

Are encoded outputs reversible?

Yes, most encoding schemes (like Base64 and URL encoding) are fully reversible. Use the corresponding decoder to get back the original data.
