Lossy compression algorithms

Lossy compression algorithms reduce file sizes by removing some data, especially details that are less noticeable to human senses. For example, in images and audio, they discard information that doesn't significantly affect perceived quality. This process results in smaller files that are easier to store and transmit but may lose some original detail. Common examples include JPEG for images and MP3 for audio. The key is balancing file size reduction with maintaining acceptable quality, knowing that some information cannot be recovered once lost.
