If you’re a Pixel 3 user, there are a few things you can do to take a screenshot on your phone. The first is to press and hold the power button and then select " screenshots." From there, you can choose how to take the screenshot. You can either take it as a PNG or JPEG. If you want to save the screenshot as a PNG, just hit “save as” and then select “png.” If you want to save the screenshot as a JPEG, just hit “save as” and then select “jpeg.”
