Google Chrome is a fast, simple, and secure web browser, built for the modern web. Chrome combines a minimal design with sophisticated technology to make the web faster, safer, and easier. Google builds powerful tools that help you connect, play, work and get things done. And all of it works on Chrome.

Speed

Chrome is designed to be fast in every possible way: It's quick to start up from your desktop, loads web pages in a snap, and runs complex web applications fast. Learn more about Chrome and speed.

Stay organized with tabs

Tabs help you stay organized, keep track of multiple pages, and multi-task. You can group tabs together for better organization or pin tabs to automatically open websites you use the most.

More control over your media

Easily control audio and video playing in any Chrome tab. Open the media hub to access controls to manage what’s playing or pop out a video to view it in picture-in-picture mode.

Simplicity

Chrome's browser window is streamlined, clean and simple. Chrome also includes features that are designed for efficiency and ease of use. For example, you can search and navigate from the same box, and arrange tabs however you wish — quickly and easily.

Security

Chrome is designed to keep you safer and more secure on the web with built-in malware and phishing protection, auto updates to make sure the browser is up-to-date with the latest security updates, and more. Learn more about Chrome's security features.

Sync Chrome across devices

From your laptop, to your tablet, to your phone, your stuff in Chrome goes where you go. When you turn sync on, you can access your bookmarks, saved passwords, and secure payment info.

And more features

Chrome has many useful features built in, including extensions, translation in the browser, themes, and more. Learn more about Chrome's newest and most-loved features.
