The need for greater data storage capacity is the cause of the emergence of various compression techniques. By compressing, large data will be reduced in size so that it can save storage capacity. Text file is a collection of characters or strings that become one unit. The solution to this problem is, how to find out which algorithm is more efficient in compressing text files between the two algorithms by comparing the performance of the two algorithms based on several parameters, namely Ratio of Compression, Compression Ratio and Space Saving. In this study, a comparison between the Even-Rodeh Code and Subexponential Code algorithms was conducted to determine the compression performance of the text file, so that in this study we were able to learn which algorithm was better used for compressing text files between the two algorithms.Keywords: Compression, File Teks, Algoritma Even-Rodeh Code, Algoritma Subexponential Code
