CAB is a archive format: it stores data in the CAB format. IMG is a document format that stores data in the IMG format. This extracts the document from the archive so it can be opened directly. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. Converting between these two formats is common when the source application does not support IMG natively or when the target platform only accepts IMG. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
