How do I convert a RAR archive to CPIO?

Upload your RAR file to the converter. The tool extracts the archive and repackages the contents into CPIO format, preserving directory structure and file permissions. Once processed, download the resulting CPIO archive.

Why convert from RAR to CPIO?

RAR is a proprietary compressed archive used mainly for file sharing, while CPIO is a Unix-standard archive format used by package managers like RPM and for initramfs images. Converting RAR to CPIO enables use in Linux-based workflows and system boot processes that require CPIO, avoiding proprietary compression dependencies.

Does converting RAR to CPIO preserve file permissions, ownership, and timestamps?

Yes, the conversion copies files from the RAR archive into CPIO format, preserving Unix file metadata such as permissions, ownership, timestamps, and directory structure. However, RAR-specific compression methods are not retained because CPIO is normally an uncompressed format; you can recompress the CPIO archive afterwards if needed.
