Abstract: Modern telescope facilities produce huge amounts of image data, but high storage costs limit possible gains from this wealth of images. Compression could help decreasing the required storage space and transmission time for an on-line distribution of images. By applying lossless compression, the costs for storage of primary data can be reduced without degrading the valuable data. An overview of existing lossless compression techniques for raw astronomical images is given here. An illustrative sample of images is used to measure the compression ratios and to verify the losslessness of selected methods that claim being lossless.
