Systems and methods for providing access to an information stream in a format customized for a receiving device involve a network-based information storage and distribution system for receiving, storing, and distributing an information stream to a user of the information stream over a network. The system receives media files and converts the media files into multiple formats. When a user attempts to access the media files, such as by browsing a site containing the media files or clicking on a link to the media files, a determination is made as to the type of device attempting to access the files. A database of devices and what file formats, resolutions, codecs, etc., they support is consulted to select a file format suitable for that device. Then, the selected media files are displayed or made available for download or transmission to the user's device in a format compatible with the particular device.
