A limited-bandwidth network electronic data communication server includes an electronic data transmission server and a network terminal in communication with the electronic data transmission server over a communications network. The electronic data transmission server includes a data receiver for receiving a request for transmission of an e-mail attachment to a network terminal over a communications network. The e-mail attachment includes content and data defining the presentation of the content. A data processing system is in communication with the data receiver for converting the e-mail attachment into a less memory-intensive data format. The data processing system is configured to perform the conversion by extracting the content from the e-mail attachment without the presentation data. A data transmitter is in communication with the data processing system for transmitting the extracted content to the network terminal over the communications network without the presentation data.
