Disclosed are various embodiments for pre-fetching resources referenced on a network page using a browser application executable on a client device. A network page predicted to be accessed by a user of a browser application may be identified that references resources, such as image, video, text, and multimedia resources. A prioritization of retrieval may be determined for the resources according to retrieval criteria. The browser application may retrieve at least a portion of the resources according to the prioritization of retrieval and store the retrieved sources in memory, thereby causing the network page predicted to be accessed to render more quickly, when accessed.
