The actual application example of the webp image is the demonstration of the webp image. For my example, I want to show some quality and size differences, so I save the same images in various formats and quality levels for comparison. I actually display the screenshot of the image in my image editor. For these examples, I use Paint.net with a webp plugin. When I upload these images to this website, the size of these images will be reduced a little, so they may look more different than the actual appearance, but I hope they can provide a good comparison.
This is the image I took from Unsplash. This is the JPEG file, which reduces to 800 pixel width and is stored at 98%. This is a 237kb file.
This is the same image saved as PNG. This is a 1.09MB file.
This is the same image saved as a webp. It is also stored at 98% of quality. This is a 199kb file.
This is the same webp file saved as 34%. This is a 35KB file. It is difficult to see any difference between images.
The end of the end
This is our view of what webp and what are webp files. This format greatly reduces the size of the image file, saves a lot of space and shortens the loading time. The main disadvantage is that it is only compatible with a few browsers. Fortunately, for those who use compatible browsers, you can use a plug -in to convert your current library to webp, and provide common file types for those who cannot view the webp format. 
Webp is an interesting format. Since it comes from Google, I hope it will eventually become popular and replace the image standards of the network. It has existed since 2010, so even if it has existed for a while, its development is slow. The saving of the file size and loading speed makes it worth using the plug -in image to provide visitors who can use them; this is free speed.
