When using the
f_auto parameter, the actual format to be fetched is determined on the CDN level. Therefore the component
f_auto must remain visible to the CDN and cannot be used within a named-transformation.
UPDATE: While setting
q_auto:good) within a named-transformation is supported, when obscured from the CDN, it prevents Cloudinary from accommodating the quality level to the "save-data" client-hints header. For more information see the documentation.
