A data compression method utilizing a series of rules which are chosen for best compressing selected data. Rules are provided for converting each datum into a binary value, and encoding this binary value into a variable-width bit field (step 1). Rules are provided for automatically increasing or decreasing the binary field width which encodes the next data value, based on the current field width and encoded data value (steps 4 and 5). An escape code is used to increase the field width for the next encoded value (step 2). A rule for efficient run=length encoding of repeated values or codes may also be included.
