Lossy compression is a technique that reduces the size of a digital file by discarding some of the original data. It is a popular method used in multimedia applications to reduce file sizes while maintaining reasonable quality. However, some people refer to this technique using different terms. For instance, some use the term "destructive compression" to describe the lossy compression technique. Others refer to it as "irreversible compression," "high-compression," "quality-reducing compression," or "exit compression." Despite the different terms used to describe lossy compression, the fundamental concept of discarding data to achieve smaller file sizes remains the same.
