Snapchat generates around 400 million photos per day via its mobile app, according to its CEO Evan Spiegel, quoted by the website TechCrunch. This means that the photo-sharing app has surpassed Facebook, where users upload 350 million photos per day on average.

To be more precise, the total number of photos shared temporarily through Snapchat each day is roughly equal to the combined total shared through Facebook (350 million) and Instagram (50 million).

Snapchat's defining feature is the ability to determine how long an image remains visible to one's contacts. As a result, the app has become a more frivolous and fun way to share funny, embarrassing or even naughty photos with reduced risk of them falling into the wrong hands.

This revelation of the total volume of photos being shared on Snapchat comes at a time when the American start-up is the focus of some astonishing rumors. Facebook is rumored to have bid $3 billion to acquire the film, while Google is reportedly willing to pay $4 billion.

The Snapchat mobile app is available on the App Store (iOS) and on Google Play (Android).
