The SDK builds delivery URLs. It does not upload files or read your local project directory.
Use a CDN endpoint’s public URL namespace in frontend code, never a secret
cvly_... API key. Follow the Image CDN setup guide if you have not created an endpoint or origin yet.
CDN SDK or API SDK?
Use@convertly-sh/image for on-the-fly image delivery, responsive srcset generation, automatic formats, and edge caching. Use an API SDK when you need to convert, compress, trim, remove backgrounds, process, or store files. Many applications use both.
