BINHEX file encoding converts a binary file into a hexadecimal text representation. This allows the file to be transmitted as the text of an e-mail message across a variety of mail servers and network types. BINHEX encoding and decoding is frequently used to transmit files between the Macintosh and PC platforms. BINHEX-encoded files commonly have an .hqx file extension.
