When would you use a lossy compression method?
When you need to reduce the file size significantly.
When quality is not a primary concern.
When data loss is completely unacceptable.
When you want to ensure that the original data is always reconstructible.

Lossy compression is used to minimize file size, so that data can be transferred more efficiently. Note that some data is lost with this compression method.
