Nick Cobler, 37, John Campbell, 46, and Dave Smith, 28, said keiselbeardme.com allows Internet users to upload their pictures and see what they would look like sporting the player's facial hair, the Pittsburgh Tribune-Review reported Thursday.
Cobler said the idea came from a Facebook profile picture he made of himself with Keisel's beard.
"I laughed so hard when I posted it. I thought, 'How great would it be if everyone could do that -- and sport the super beard of the Super Bowl?'" he said.
Keisel said the creators can count him as a fan of the site.
"I think it's hilarious," he said. "A lot of them are putting them on their dog or their baby or something like that. It's pretty funny."
