What is Image Compression?

Image compression is the process of reducing the file size of digital images while maintaining acceptable visual quality. This is achieved by removing redundant or unnecessary data from the image file.

Key Concept: Compression can be either lossless (no quality loss) or lossy (some quality loss for smaller file sizes). Most web images use lossy compression to achieve significant file size reductions.
