FAQ

Can the extractor handle repeating parameters and array syntax?

Yes. It recognizes repeating query keys (e.g. tag=1&tag=2) and bracketed array parameters, grouping them into clean arrays.

Does it automatically decode percent-encoded special characters?

Yes. Encoded values (e.g. %20 or %26) are automatically decoded into human-readable characters.

Are sensitive tokens or query parameters safe?

Yes. URL parsing executes locally using native browser URLSearchParams APIs without transmitting query data over any network.
