Google Web Accelerator（Google网际加速器）是使用「Google全球计算机网络」技术的一款网页浏览加速软件。由于此软件仍处于测试阶段，对某些网页的加速效果会不明显，而且对加密网页（如Https）无任何加速作用。本质上它是一种代理中转软件。Google Web Accelerator便于使用，下载并安装后即自动加快网页的加载。

Google Web Accelerator was a web accelerator produced by Google. It used client software installed on the user's computer, as well as data caching on Google's servers, to speed up page load times by means of data compression, prefetching of content, and sharing cached data between users. The beta, released on May 4, 2005, works with Mozilla Firefox 1.0+ and Internet Explorer 5.5+ on Windows 2000 SP3+, Windows XP, Windows Server 2003, Windows Vista and Windows 7 machines.
