SiteCapture for Mac lets you take screenshots of multiple Web pages, simultaneously, without even opening your browser or viewing the page. Keep track of all of your sites on a regular basis with just a couple of clicks through this handy and streamlined app.
The intuitive interface of SiteCapture gives you quick access to all of the app's features. You can choose the sites you want to capture from the Bookmarks Bar, Bookmarks Menu, Apple Reading List, or YouTube. Just select your source from the drop-down menu, and the list of sites will show up in the main box on the left-hand side of the interface. Select and deselect items using the check boxes, and then choose the location you'd like to save the images to. Image formats available for saving include JPEG, TIFF, BMP, GIF, and PNG, and you can choose to save full-size images, or constrain proportions with the tools on the lower right-hand side of the screen.
When you're ready, click "Generate Thumbnails" to begin your captures, and the images will briefly show up in the box on the right side of the interface as they are taken. The only real drawback to this program is that there is no Help file, but since the interface is so streamlined, it's not too hard to find your way around. The program is free, it works quickly, and it saves accurate images in the quality that you choose. So if you'd like the ability to take multiple screenshots at once, this is a good option to try.
