</tr> </table> WebArchive is both:

• a file format for rich web content
• a class within a software framework.

Opening .webarchive files: hints

On Windows:

• if a received .webarchive is not associated with a supporting application, drag the file to a window of the application
• you may opt to always open .webarchive files with a preferred application, such as Safari.

Microsoft Office Word 2007 can open a WebArchive file, and save as a web page, but integrity is not great; Office lacks native support for the format.

Alternatives

• MHTML

Some browsers save a directory of inline resources, such as images, alongside an html file. The collection is sometimes compressed, like the .war format used by Konqueror.

WebArchive: the class

This class is both:

• within the open source WebKit project
• within Mac OS X 10.3.9 and later, in the WebKit Objective-C Framework.

Use the WebArchive class to archive webpages, or place a portion of a webpage on the pasteboard, or to represent rich web content in any application.^[1]
