Opera Mini's primary purpose is to allow users to browse the web on mobile devices, such as iPhones and Android-based smartphones. The application includes a number of unique features that improve on the default browsers included with phones.
A key feature of Opera Mini is the use of compression to improve the speed at which websites load. This compression has a beneficial side effect of reducing how much mobile data one uses. Another key feature of Opera Mini is the ability to browse the web privately, ensuring that history information is discarded at the end of a browsing session. Opera Mini also includes a number of customization and synchronization tools, allowing users to personalize and coordinate their browsing across computers and mobile phones.
