Compression Artifact

/kəmˈprɛʃən ˈɑːrtɪfækt/noun
ELI5 Mode🧒

A compression artifact is a visual or auditory distortion that appears in digital media, like images, videos, or audio files, as a result of data being compressed to reduce file size. These imperfections, such as blurring, pixelation, or blocky patterns, arise from lossy compression techniques that discard some information, making them a common trade-off in everyday streaming and online sharing where storage and bandwidth are at a premium.

Did you know?

Did you know that compression artifacts in JPEG images can reduce file sizes by up to 90% compared to uncompressed versions, which is why billions of photos are shared daily on platforms like Instagram, but this often means losing subtle details that the human eye might not immediately notice until zoomed in?
