VHDX is a document format: it stores data in the VHDX format. DEB is a archive format that stores data in the DEB format. This packages the document into a compressed archive for smaller transfer size. 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 DEB natively or when the target platform only accepts DEB. 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.
