UC Browser is a mobile browser developed by UCWeb (also known as UC Mobile). The browser uses cloud acceleration and data compression technology. UC Browser's servers act as a proxy which compresses the data of web pages before sending it to users. This process helps load web content faster. The browser can adapt to different network environments and support multi-file format downloading. In addition, UC Browser has HTML5 web app and cloud syncing features. This browser can allow some websites to avoid standard signature detection.
