Add-on summary

Analyze keywords

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)
