The Cupertino firm replaced its homepage with a video homage to the tech mastermind and a letter from his successor, Tim Cook.
The clip features an array of black and white photographs of Jobs from throughout his career, set against a series of audio quotes from the former Apple head spoken during product launches.
Cook said in his letter: "Steve's passing one year ago today was a sad and difficult time for all of us. I hope that today everyone will reflect on his extraordinary life and the many ways he made the world a better place.
"One of the greatest gifts Steve gave to the world is Apple. No company has ever inspired such creativity or set such high standards for itself. Our values originated from Steve and his spirit will forever be the foundation of Apple. We share the same privilege and responsibility of carrying his legacy into the future.
"I'm incredibly proud of the work we are doing, delivering products that our customers love and dreaming up new ones that will delight them down the road.
"It's a wonderful tribute to Steve's memory and everything he stood for."
Jobs died one year ago today following a battle with pancreatic cancer. The flag at the civic centre in Apple's home city of Cupertino will be flown at half-mast today.
