DEB is a archive format: it stores data in the DEB format. RAR is a archive format that compresses files with the proprietary RAR algorithm, typically achieving better ratios than ZIP for mixed-content archives. 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 RAR natively or when the target platform only accepts RAR. 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.
