It renders web pages at lightning speed. It works on iPad, iPhone, iPod touch, Mac, and PC. It shows you your favorite sites at a glance. And it’s so smart, it even checks your spelling and grammar. Meet Safari, a browser unlike any you’ve ever seen.

Even Greater HTML5 Support
Web standards are the future of the Internet. The world’s most innovative browser, Safari continues to lead the way in support for HTML5. Safari 5 supports over a dozen new HTML5 features that allow developers to create interactive content and media experiences that work right in the browser — without the need for third-party plug-ins.
Full-screen view and closed captions for HTML5 video.

In Safari 5, HTML5 video can deliver an even richer, more accessible experience. Watch video embedded with the HTML5 video tag in full screen. If the video includes closed captions, simply click the closed-captions button in the controls to display them.
Location services.

Find businesses near you and get directions even faster. With support for the HTML5 geolocation standard in Safari 5, you can choose to share your location with websites that use it to give you helpful location information — like showing you the nearest post office or ATM. Rest assured, you’re always in control of how your information is shared. When you visit a geolocation-enabled website, Safari asks you before sharing your location. And you can turn off location services all together.

Better Performance
Faster Nitro Engine.

The world’s fastest web browser gets an engine upgrade. Enhancements to the Nitro Engine in Safari 5 mean you experience web browsing at greater speeds than before.

Powered by the Nitro javascript engine, Safari 5 on the Mac runs javascript 30 percent faster than Safari 4, 3 percent faster than Chrome 5.0, and over twice as fast as Firefox 3.6.
DNS prefetching and improved caching.

Behind the scenes, Safari employs a technique called Domain Name System (DNS) prefetching. If you’re on a web page with links, Safari finds the links and looks up the addresses. Click one of the links, and Safari quickly loads the web page for you. And improved page caching means more of the pages you viewed in the past load faster than before.
