Lossy Compression
Explore lossy compression techniques that reduce file sizes by eliminating less important data, with applications in JPEG images and MP3 audio. Understand how this method achieves high compression rates by allowing minor quality loss, balanced against file size savings for efficient storage and transmission.

What is lossy compression?
Lossy compressions allow a reduction in the size of a file by removing unnecessary or less important data. However, removing data can distort the original file and, therefore, lossy compressions are only used where a slight distortion to a file is tolerable because sometimes the loss in detail is barely noticeable by humans. The amount of data reduction possible using lossy compression is much ...
