Abstract

In the field of computer science, data compression is essential in the process of data transfer because it reduces file size without losing information. Issues that depend on the characteristics of the text can greatly affect the effectiveness of any compression algorithm. Consequently, each traditional compression algorithm has its own strengths and limitations. Therefore, a highly efficient compression method that achieves higher compression ratio is needed. In this paper, based on the sequential implementation of Huffman, RLE and LZW algorithms, a hybrid data compression method has been proposed. The algorithms have been individually evaluated and compared in terms of compression ratio and compressed file size. We conclude that in terms of compression ratio and compressed file size, LZW is better than Huffman and RLE. The results show that the proposed hybrid algorithm achieves the highest average compression ratio is 2.42 and the lowest average compressed file size is 1138.5 or less compared to the individual implementations of the algorithms. Thus, it can be concluded that the proposed hybrid method enhances lossless text compression in terms of compression ratio and file size according to compression metrics.
