SnipSVG has two ways for using the pictures you create: You can use the Export menu to use them directly or share them with other applications via a number of methods. Or you can save them directly as SVGs for use in your own web pages, along with the code you need for embedding there.
Which method you use depends on what you are going to do with the images, of course.
Screenshots and direct use in other programs like Help+Manual
Use the Export menu for this. It provides all the methods you need, and more, for getting your images into other programs in the most efficient way possible.
Web development
The instructions in Adding SVGs to Web Pages are what you need to use SnipSVG SVGs on the web, particularly if they include hyperlinks, animations or video content.
