What and how do I optimize images?
The successful way is to understand the idea and meaning behind it before you go at it. Optimizing images means reducing the file size with almost no loss in quality.
There are two types of quality optimization.
- Lossless- a slight reduction in file size with no change in quality.
- Lossy – a much more significant reduction in file size, but there might be some loss in image quality. There are different levels of lossy compression – some might not even be noticeable to the human eye, while more aggressive algorithms might have a noticeable impact.
