Buzsaky was offered a new deal at the end of last season but believes his future lies elsewhere, ending his four-year spell in west London.
"The club is thankful to Akos for his contribution and wishes him every success for the future," read a statement on the club's official website, www.qpr.co.uk.
Buzsaky played only a limited role in QPR's escape from relegation last season, scoring two goals in 21 appearances.
