How to take a screenshot on Windows, Mac, iPhone, and Android
Quick answer: Use the built-in screenshot shortcut for your device. On Windows, Snipping Tool gives more control; on phones, the hardware-button combination depends on the model.
Windows
Use Snipping Tool or the Windows screenshot shortcut to capture all or part of the screen. Save or copy the result from the capture interface.
Mac
Use macOS screenshot shortcuts to capture the full screen, a selected area, or a window. The screenshot options let you choose where the file is saved.
iPhone and Android
Most recent phones use a combination of the side/power button and a volume button, but the exact shortcut can vary by device. Check the manufacturer’s instructions if the standard combination does not work.
