SPARQL Query, to output a new graph:

PREFIX rdf:     <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
CONSTRUCT { [] rdf:type rdf:Statement ;
                rdf:subject ?s ;
                rdf:predicate ?p ;
                rdf:object ?o . }
WHERE { ?s ?p ?o }

or to change in place, removing the old data:
SPARQL Update:

PREFIX rdf:     <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
DELETE { ?s ?p ?o }
INSERT { [] rdf:type rdf:Statement ;
             rdf:subject ?s ;
             rdf:predicate ?p ;
             rdf:object ?o . }
WHERE { ?s ?p ?o }
