Snapchat is a messaging app that allows users to send and receive messages, photos, and videos. The app has a feature called “Screenshots.” When you take a screenshot of something on Snapchat, you can save it as a file or share it with others. To screenshot on Snapchat without them knowing, you first need to set up your Snapchat account and sign in. Then, open the Screenshot tool in the bottom left corner of your screen. Once you’re in the tool, select the thing you want to screenshot and click on the “Screenshot” button. Once you’ve taken a screenshot of something on Snapchat, you can save it as a file or share it with others. If someone else wants to see your screenshot, they can open it in their own app and view it however they like.
