Overcompression

Part of speech: noun

Definitions

1. The act of applying excessive compression to data, which may lead to loss of quality or detail in the process
2. A condition resulting from too much pressure applied to a digital file, resulting in potential degradation of information
3. An occurrence when the compaction of information is taken too far, often causing artifacts or misrepresentation of the original content

Etymology: "Overcompression" is a straightforward formation: the prefix "over-", meaning excessive or beyond the proper amount, attached to "compression", the act of squeezing something into a smaller space or volume. Put together, the word names the act of compressing something too much, a step past the point where reduction is useful. In practice the term is most often applied to digital data, such as audio, images, and video, where aggressive compression shrinks files by discarding detail. The "over-" prefix signals that the trade-off has tipped: the file is smaller, but the loss of quality or information is no longer acceptable. Its meaning is therefore tied directly to the idea of a boundary that has been crossed.
