Lossy compression sorts the data and removes the bits it thinks it doesn’t need to still provide a good experience.

RAR files use lossless compression to shrink file sizes. As data storage uses a lot of redundancy such as storing the same information in multiple places, listing data literally instead of efficiently and indexing every single piece of data, tidying all that data up can save a serious amount of space. To repeat a much-used example, if a file includes the following data bits: AAAABBBBCCCCDDDD, this is how it would be stored without compression. If you added that data to a RAR archive it would be compressed to A4B4C4D4. This refers to the fact there are 4 As, 4Bs, 4Cs and 4Ds. As you can see from that super-simplified example, a lot of space can be saved. Multiply that by millions of bits in an average file and you can see how RAR compresses files.
