Giroud is France's second top all-time scorer, two goals shy of Thierry Henry's national team scoring record of 51.
But the AC Milan forward, who lifted the World Cup with France four years ago in Russia, has failed to deliver on the sport's biggest stage with his strike at the finals in Brazil in 2014 being the only one from his two previous tournaments.
In total he has scored three goals in World Cup and Euro tournaments in his career.
"Yes, I scored one in 2014 (World Cup) and a few at the 2016 Euros. It's important for the team to score. I'll give it my 200% for the team," Giroud told a news conference on Thursday.
"For me it's kind of a blessing to have the opportunity to play for my country in a third World Cup."
"Obviously I have this target in my head to beat Thierry (Henry's record) but the main goal is that of the team to go as far as possible and if I get the chance to go closer to him (Henry) I'll take it."
France start their World Cup title defence against Australia on Tuesday before facing Denmark and Tunisia in Group D.
Giroud was recalled to the national team in March after a nine-month hiatus following France's early Euro 2020 exit, and has been in good form for Milan in recent months.
"To win one World Cup is obviously such a big a childhood dream. To get a second one would be amazing. As a competitor I have no limits I am still hungry," he said.
"I want to play as far as my body allows me with my advanced age. I am closer to the end of my career than to the beginning.
"The determination and mental motivation is everything in sport so that's why I am never satisfied. I want to do more and more," he said.
