Lossy compression
A useful mental model for the technology shaping daily life.
The useful idea
- The useful idea
In information technology, lossy compression, or irreversible compression, is the class of data compression methods that uses inexact approximations and partial data discarding to represent the content.
- How it works
These techniques are used to reduce data size for storing, handling, and transmitting content.
- Why it matters
Higher degrees of approximation create coarser images as more details are removed.
Why this matters
Use Lossy compression as a lens when judging what a digital tool can — and cannot — do.
