WEBP file open in Google Chrome 60
WEBP files are often created when a Chrome user downloads an image from the web browser by dragging and dropping it on the desktop or right-clicking the image and saving it in the WebP format. If you come across a WEBP file you can open it in the Chrome or Opera web browsers or with a graphics editor, such as Pixelmator, Image Magick, IrfanView, or XnView.
The WebP format is based on On2 Technologies technology that was acquired by Google. The format was introduced in 2010.
NOTE: The WebP Codec for Windows plugin listed below enables Microsoft Windows Photo Viewer to open WEBP files.
