SiteSucker is a free web browser application designed for Mac users, allowing them to download entire websites for offline access. By entering the homepage URL, users can grab all resources associated with the site, including images, backgrounds, and files. The software is especially useful for users who need to ensure that a website is always available without an internet connection.

The application features various customizable options such as setting the maximum number of levels and files to download, as well as establishing size limits and specifying file formats. It can even extract links from Flash animations, although it does not support Javascript links. However, users should note that SiteSucker only processes specific HTML tags, meaning links embedded in other tags may not be captured.
