Snapchat lets you swap with any face in your camera roll — and it's insanely fun

By now you've probably seen people swapping faces in Snapchat. It produces a hilarious and often frightening effect.

Until now, you could only face swap with someone if you were both in the camera view of Snapchat's app. It was an inherent limitation that kept the feature reserved for people you're physically next to (or maybe an inanimate object that looked like a face if you were lucky). 

Now Snapchat lets you face swap with any photo in your phone's camera roll, which is a game changer. It's insanely fun to play with.

You can find Snapchat's camera roll face swap by tapping and holding on your face to activate the app's list of special lenses.

You'll eventually find this purple face swap lens next to the original yellow one. It will automatically pull up photos in your camera roll that have faces to swap with.

Just tap on each photo to have the face placed over your own. Here I am as Kylie Jenner, Kanye West, Nic Cage, and DJ Khaled:
