compression questions

Compression is the application of Data compression on digital images. The reason we use it is to reduce redundancy of the image data in order to be able to store or transmit data in an efficient form. It basically uses less space without losing image quality.

The difference between lossy and lossless is no information or data is lost with lossless, whereas with lossy everytime you save it in jpeg form it condenses information and data is lost.
