Convert ZIP to TAR — Free Online Converter

ZIP is the universal archive format with per-file DEFLATE compression and random access, supported by every operating system natively. TAR is the Unix file-bundling format that stores files in an uncompressed stream with full preservation of Unix permissions, symlinks, ownership, and timestamps. TAR has been the foundation of Unix archiving since 1979.

Converting ZIP to TAR transforms a cross-platform compressed archive into an uncompressed Unix-native file bundle. This conversion is useful when you need raw tar input for Unix package building, Docker layer operations, or subsequent compression with an algorithm of your choice. The TAR output preserves Unix metadata more faithfully than ZIP's cross-platform compromise.

TAR is the base format for Unix packaging (deb, rpm), Docker images, and virtually every build system in the Linux ecosystem. When starting from a ZIP file, converting to TAR makes the content usable by these tools. Docker's COPY and ADD instructions natively handle tar streams. Build systems that produce reproducible archives often require tar as input.

TAR also preserves Unix metadata that ZIP handles poorly. Symbolic links, hard links, device files, extended attributes, and precise uid/gid ownership are all first-class features of the tar format. ZIP stores some Unix permissions via external attributes but has no standard representation for symlinks or device files. Converting to TAR restores full Unix metadata fidelity.
