WEBPファイルとは？
A WEBP file is an image saved in the WebP raster image format developed by Google for displaying images on the web. The WebP format supports both lossy and lossless compression and can produce smaller image files than formats such as JPEG and PNG while maintaining similar or better image quality. WEBP files also support transparency and animation.
詳細情報
Google developed WebP using technology it acquired from On2 Technologies in 2009 and introduced it in 2010 as an open image format. The format has since gained support for additional features, including animation, transparency, and metadata.
WebP files use a container based on the Resource Interchange File Format (RIFF), a format developed by Microsoft and IBM. WebP's lossy compression uses technology from the VP8 video codec, while its lossless compression uses a separate algorithm designed specifically for WebP images.
