This extension allows converting from WebP (or any other format) to PNG or JPEG. There also is a button to re-request the image masquerading as Internet Explorer 11 (you might need to click it a second time because Firefox likes to serve the cached image), and a button to send animated WebP images to ezgif.com for conversion to animated GIFs. New in version 1.5.1 (forthcoming): When the script can't inject buttons into a page, a new popup window will appear with possible workarounds. New in version 1.4: New button to Copy the image to the Clipboard in PNG format. Permission needs to be enabled on the Add-ons page (click the gear/wheel button on the add-on button bar, then click Permissions, then click the slider switch for "Input data to the clipboard). If you want to discourage sites from sending webP format images at all, especially if you are having trouble saving GIFv files, check out my other extension: Don't "Accept" image/webp. Configuring the context menu item These are the default actions, but you can switch them around to fit your needs (on the Options panel): * Click "Save webP as..." to show format/quality buttons overlaid on the image * Shift+click "Save webP as..." to save in PNG format * Ctrl+click "Save webP as..." to save in JPEG format at 92% quality (on Mac, use Command+click) Custom save folders Extensions can only save under your Downloads folder, but you can set up date or site folders to help keep organized. Troubleshooting The button bar may not appear and images may not be saved if scripts are blocked from running in the page (for example, by the NoScript extension). Google Photos As of August 6, 2023, the add-on cannot construct a valid and useful file name to save from the slideshow style viewer on Google Photo. Please right-click > Open Image in New Tab if you need to convert an image from Google Photos until I can find a solution. Notes I regret having to use the "All sites" permission, but most images these days load from a different server, and that creates a cross-site access problem (canvas taint) that often blocks the extension from saving unless it has permission in advance. In a future release, I will try to offer a different approach that uses fewer privileges.
