The screen captures that you complete can be stored in different formats, like PNG, JPEG, TIFF and GIF. It is also possible to use SiteShoter to convert HTML files from your hard drive to image files. What's more, you will be able to use the software properly by means of its delicate, simple and functional interface, or from the command line. If you opt for the first option you will only have to specify the URL and a location to place the resulting file on your computer to take and save the captures.
If you want to complete website captures and you want to save yourself the bothersome procedure of editing the images later, you should try SiteShoter.
