näytönkaappaus

Näytönkaappaus, also known as a screenshot, is a digital image that captures what is currently displayed on a computer monitor, smartphone, or other screen-based device. It is a common method for documenting visual information, sharing content, or troubleshooting technical issues. The process of taking a näytönkaappaus varies depending on the operating system and device.

On most personal computers running Windows, a näytönkaappaus can be taken by pressing the Print Screen (PrtScn) key, which copies the entire screen to the clipboard. Alternatively, pressing Alt + Print Screen captures only the active window. The Windows key + Print Screen combination saves the näytönkaappaus directly to a designated folder. macOS users can use the Command + Shift + 3 shortcut to capture the entire screen or Command + Shift + 4 to select a specific area. These images are typically saved to the desktop.

Mobile devices like smartphones and tablets also offer built-in näytönkaappaus functionality. On Android devices, it is often achieved by simultaneously pressing the power and volume down buttons. iOS devices typically use a combination of the side button and volume up button, or the home button and power button on older models. The resulting images are usually stored in the device's photo gallery.

Näytönkaappaus is a versatile tool used for various purposes, including saving important information from websites, illustrating steps in a tutorial, documenting error messages for technical support, or sharing visual content with others. The file format of a näytönkaappaus is typically PNG or JPG, with PNG being preferred for its lossless compression, preserving image quality without pixelation.
