WEBP to JPG — Reverse — for tools that don't accept WebP yet
WebP → JPG is the compatibility fallback — Facebook Ads Manager, some CMS uploaders, print-lab dropboxes, and older third-party services still reject WebP. Convert to JPG when your source is a WebP download (from a Chrome browser save-image, or an image scraped from a modern site) and your destination doesn't support it. Expect 25-35% larger file size for the same visual quality.
