Abstract
A content preview of a content item stored in an online storage system can be viewed on a client device without the content item itself being downloaded to the client device and without the use of software associated with the content item being installed on the client device. Furthermore, data storage and processing requirements can be minimized by creating and storing only one content preview for each unique content item. The content item can be identified by using the content item as a hash key in a hashing algorithm. The resulting unique identifier can be used to search a preview index that lists all created content previews and their location. A content preview is only created if one does not exist. The unique identifier can be used to locate the content preview and return it in response to a preview request by a client device.
