/v1/convert
Submit files to /v1/convert, poll the job endpoint, then download outputs programmatically.
Animated, sequence, or multipage inputs need explicit frame/page handling.
Converting HEIF to L16 decodes the source image and writes a L16 output. Use this route when L16 is a better fit for compatibility, file size, editing, or delivery.
Known metadata support: Exif, XMP, item properties, thumbnails, derived images.
