What is compression?

Compression is the original size being reduced in size so it can reduce download timings, be quicker to load the file and save space that is not needed . There is two types of compression, lossless and lossy which are different.

lossless

In lossless compression in contrast to lossy, it compresses data in a very smart way, it does not lose any valuable data in a file. it is also involves recreating data in the file that is lost, which can be stored in a further data if wanted.

lossy

Unlike lossless, lossy removes data from files when is being reduced in size, once it is compressed the data lost cannot be restored to and the file can not be recreated to its original quality.
