Lossy compression is a technique that reduces file sizes by discarding less critical information, optimizing data for multimedia, cloud services, and more. It leverages human perceptual limits to maintain quality while minimizing storage needs. This method is vital in audio, video, and image processing, as well as in fields like genomics and big data analytics.

Lossy compression definition
Data encoding method reducing file size by removing non-essential information.
01
Lossy vs Lossless compression
Lossy discards data for size; lossless retains all data allowing perfect reconstruction.
02
Lossy compression application
Used in audio, video, images where exact original data fidelity is unnecessary.
