WebLossy compression disadvantages. Loss of detail — When you compress an image, you can lose nuance, colour and depth. This can be fine for everyday web use, but if you’re using your photo in a bid to turn heads, the image might fall flat. Irretrievable data loss — When you use lossy compression, you can’t retrieve the data. 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. These techniques are used to reduce data size for storing, handling, and transmitting content. The different versions of the photo of the cat on this page show how higher degrees of approximation create coarser images as more details are removed. This is opposed to lossless …
