A screen shot is an image that shows exactly what was showing on your computer screen when it was taken. You can convert a screen shot or any other image to a .jpg (or "JPEG") to compress a file or reduce an image's file size. You might also need to convert a screen shot to a .jpg to upload your image to a website or message board. You can use Microsoft's free Paint program, which is included on PCs for free, or most other graphics programs to convert a screen shot to a .jpg.

Press the "Prt Sc," "Print Screen" or "PrtScn" key on your keyboard. You may have to press the "Fn" key and the print screen key simultaneously to capture the screen shot, if that's required by your particular keyboard.
Step 3
Press the "Start" button in the lower-left corner of your screen, type "mspaint" into the search bar at the bottom and press the "Enter" key on your keyboard.

Step 6
Click a location for the .jpg image on the left panel. Double-click any folders you wish to place it in from the main panel, if necessary. Click the "Save as Type" drop-down arrow at the bottom and choose the "JPG (.jpg, .jpeg)" option. Click the "Save" button at the bottom. Your screen shot is now saved as a .jpg image.
