Lossy Vs Lossless Compression

Lossy Vs Lossless compression

Lossless compression is a way of compressing images that doesn’t remove any of the original data. This method of compression takes up much more memory than lossy compression, however, the loss of detail and information in digital images or any other file type are much less i.e. the quality of the image or file will remain equally as high as before the file was compressed.  

Any file formats such as Raw, or CR2 (canon format for raw files) etc are all exmaples of files that benefit from lossless compression.

Lossy compression is a memory efficient way of storing images and other file types. This is because when lossy compression takes place data and information from the file being compressed is deleted so as to reduce it’s memory uptake. Usually, information will be deleted in a way that is noticeable to any future user of this file.

For example, file formats such as Jpegs, png and gif are all compressed with lossy compression.

When you are simply looking at a jpeg image it will be difficult to notice the difference between that and it’s counterpart raw image. However, when you come to edit the image the lack of information in the jpeg image will be noticeable.
