Microsoft added support for WebP images in Microsoft 365, allowing users to insert WebP pictures into Word, Excel, PowerPoint, and other Office applications. WebP images offer high quality with smaller file sizes compared to traditional formats like JPEG and PNG.
WebP is an image format unknown to many people but is increasingly used by web sites. It’s a format made by Google to replace JPG, PNG and GIF with images of the same quality but smaller file sizes.
The format is widely supported in modern browsers. Web sites can be setup to send .webp versions of images when possible with other formats (like .jpg etc) sent otherwise. Modern Google Chrome, Edge, Firefox and Safari browsers all support WebP.
WebP appears as another image type in the Insert | Image dialog or just drag and drop a picture from Explorer into the document, sheet or slide.
