WebP 的好處

  1. The greatest advantage of WebP is that the format allows a much smaller file size than the conventional ones can do.
  2. The smaller size of a WebP file leads to faster data transfer and lower network burden. The file size of an animated WebP image with lossy compression is about 30% percent of an animated GIF image's file size.

    WebP (476 KB)

    The WebP file size is only 30% compare to that of GIF when saved with the quality 90.

    PNG vs WebP

    The sample image above has a transparent background. The image needs to be saved as a PNG or WebP file because the JPG format has no support for such transparency and the GIF format's image quality is very poor compared with other formats. Saving the image as a WebP file reduces the file size to 15.9% of a PNG file's size with almost the same quality.

  3. WebP allows you to be freed from the limitations of the GIF format.
  4. The GIF format supports only 256 different colors, which means that saving an image as a GIF file mostly results in poorer image quality than before. The quality deterioration occurs more severely if the original image contains a wide range of natural colors. The GIF format supports only 256 different colors, which means that saving an image as a GIF file mostly results in poorer image quality than before.

    The samples above show that the GIF image cannot display the color spectrum correctly and the deterioration occurs. WebP has no such limitations and supports up to 16,777,216 colors.

  5. Anyone can freely create, use, and distribute WebP images.
  6. Google has a patent on the format but asks for no royalty to use it. Anyone can create, use, and distribute WebP images without worrying about costs.

  7. There is no need to think about which format to use when saving images.
  8. The JPG format is suitable for photographs of actual objects. The PNG format is for artificial or computer-generated graphics, and the GIF format is for animated images. But because WebP format has support for lossy and lossless compression, animation, and alpha channel all, you can save an image as a WebP file without consideration of the characteristics of the image.

    Honeycam can automatically decide whether to use lossy or lossless compression when saving your image as a WebP file.
