Screenshots are saved automatically as .png files on the desktop; the filename begins with “Screen Shot” and includes the date and time it was taken.
Alternate locations and file formats are possible, but it requires changing it manually.
On macOS prior to Mojave, there is a Terminal command, and there are apps that provide a GUI for this Terminal command (e.g. Onyx).
If you take screenshots through QuickTime Player, then the location can be set in the Options menu.
