All of us are familiar with jpg, jpeg, png, gif etc. These all are famous image formats. But now we have a better optimized, compressed format called Webp. In webp, the size of image is reduced considerably but quality remains almost the same.
A disadvantage of webp is that you can’t preview it normally, But it can be opened in browser only.
