If your screen shot contains a limited number of colors and you want to retain crisp lines and keep the file size small, save as a GIF file. If your screen shot contains many colors and you want to retain crisp lines and full quality, save as a PNG file. If your screen shot contains many colors and you want to make the file size small, save as a JPEG file.
Before saving your screen shot, you can use the Pen and Highlighter tools in the Snipping Tool toolbar to add markup to your capture. The eraser tool will remove marks made with the Pen and Highlighter Tools.
You may email a screen shot without saving it by using the "Send To" button on the Snipping Tool toolbar.
Go to Tools > Options to change the way the Snipping Tool operates. For instance, you can change the color of the selection outline by selecting a new ink color, or turn the outline off entirely by unchecking the box for "Show selection ink after snips are captured."
Enable the option "Display icon in the Quick Launch toolbar" if you want to keep the Snipping Tool handy for quick access. You could also right click its startup icon - select "Send To" then "Desktop" to create a shortcut on your desktop for easy access.
