This extension adds a Save as PNG, JPEG or WebP option to the right click context menu of every image.
Really simple extension to convert an image to a different format at download time. With the increase use of WebP on many sites it has become difficult to use the WebP images after they are downloaded do to the lack of support for the format in other programs. With this extension you can right click any image and "Save As JPEG" or PNG if you prefer. It can also save as WebP if you want to save same space.
