[HTML] WEBP, apng picture format

WEBP format, a graphic format developed by Google to speed up the loading of pictures. Image compression volume is about 2/3 of JPEG, and can save a lot of server bandwidth resources and data space.

As with JPEG, WEBP is a lossy compression. But Google says the main advantage of this format is efficiency. They found that "in the same quality situation, the WEBP format image is 40% smaller than the JPEG format image."

Google Browser has supported the WEBP format, opera after the version number Opera11.10 also added support, but Firefox and IE temporarily does not support the WEBP format, you can use the Flash plugin to display WEBP, of course, this will cost some performance.

In the ointment, the encoding time of the WEBP format image is 8 times times longer than the JPEG format image.

The advantage of WebP is that it has better image data compression algorithm, can bring smaller picture volume, and has the visual quality without difference.

With lossless and lossy compression modes, Alpha transparency, and animated features, the conversion effect on JPEG and PNG is excellent, stable and uniform.
