Compression is evaluated based on two primary factors: the reduction in data size (compression ratio) and the preservation of data integrity (lossless vs lossy compression). The compression ratio is the ratio of the compressed size to the original size, while data integrity refers to whether the original data can be perfectly reconstructed from the compressed data (lossless) or if some data is lost in the compression process (lossy).
