Part 2. More Knowledge about Lossy and Lossless Compression

1. What is Lossless Compression

Lossless compression is a process of compression where the size of the file is reduced without losing its quality. There is no loss of any data in the process of lossless conversion. In many situations, lossless compression is not very useful as the compressed files are almost of the same size as the original size.

2. What is Lossy Compression

Lossy compression is a process where the files are reduced and compressed in size with the loss of data from the original video. The quality of the file gets degraded with the lossy compression process, and it is irreversible. The majority of the compression tool allows choosing the percentage of the compression as there is a loss in quality. The file size gets reduced to a great extent with lossy compression that makes it easy to share and transfer the videos over an array of sources.

3. Difference between Lossy and Lossless Compression

It is evident from the above definition that there is a major difference between lossy and lossless compression. First of all, the quality of the file does not change with lossless compression, while in the lossy process, the file quality is degraded. Secondly, the file size is reduced significantly with lossy compression, but with a lossless compression process, the output file is almost of the same size as the original one. Thus, the choice of lossy vs. lossless compression depends on the type of website and its visitors it is targeted for.
