RAR is a archive format: it compresses files with the proprietary RAR algorithm, typically achieving better ratios than ZIP for mixed-content archives. DEB is a archive format that stores data in the DEB format. This conversion changes the file's encoding, compression method, and supported feature set. 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.
