Abstract	On digital image storage, the size of image will influence the use of memory. The bigger the size of an image then the bigger memory will be needed. Image Compression is the method that reduce the size of digital image. Run Length Encoding and Daubechies Wavelet Transform are methods that can be used in the process of digital image compression. In this research, Run Length Encoding method and Daubechies wavelet transformation method will be compared to decide the quality of image compression result based on running time process, compression ratio and redundancy data. Digital image used is grayscale image with Bitmap format (*.BMP). Image compression result can be returned to the original size with image decompression process. Run Length Encoding has better running time process than Daubechies Wavelet Transform, based on experiments of five different images with the same size where the average speed of Run Length Encoding method is 1,03125 second while the average speed Daubechies Wavelet Transform is 2,571876 second. Run Length Encoding method is also better based on compression ratio and redundancy data, if the image that is used does not have many pixel color differences. Meanwhile, if the image has many pixel color differences, then Daubechies Wavelet Transform method is better based on compression ratio and redundancy data.
