We Now Have a Definitive Answer on How to Pronounce "Gif"

I've never been so happy for a "soft G"

From CNN:

Although Jif is obviously pronounced with a "soft G," people often mispronounce the word "GIF," which is short for Graphics Interchange Format. It's said with a "soft G like the peanut butter and not a "hard G." That's according to creator Steve Wilhite, who made the declaration in 2013 while accepting a Webby Award.

Regardless of the official ruling, the internet has remained divided. Jif is partnering with GIPHY, a GIF search engine, to "put a lid on this decade-long debate": Both GIF and the peanut butter are pronounced "Jif."

Limited edition jars of "Gif" peanut butter are also being sold right here (get 'em while you can)
