ZIP to TAR

How to Convert ZIP to TAR Online

1. Upload Your ZIP File: Drag and drop the ZIP archive, or click "+ Add Files" to pick from your computer. Multiple ZIP files can be queued at once for batch conversion.
2. Pick Combine Mode: Default is Single Archive, which extracts the contents of every uploaded ZIP and re-bundles them into one TAR. Switch to Individual Archives to produce one TAR per source ZIP — useful when you need to keep deployments, releases, or backups separate.
3. Review Settings (Optional): Output is a plain ustar-format TAR with no compression. Filenames, directory structure, and modification timestamps are carried over from the ZIP. For a smaller file, convert to a compressed tarball instead — see ZIP to TAR.GZ, ZIP to TAR.BZ2, or ZIP to TAR.XZ.
4. Convert and Download: Click Convert, wait for the queue to finish, then download. Files are processed on our servers and removed automatically after the session — no account, watermark, or installed software required.

Why Convert ZIP to TAR?

ZIP (created by Phil Katz at PKWARE in 1989) is the default archive format on Windows and the most common cross-platform container, but it's a poor fit for Unix-style workflows. TAR — short for "tape archive," introduced to Unix in January 1979 and standardized as ustar in IEEE Std 1003.1-1988 — is what almost every Linux, BSD, and macOS command-line tool expects when you're packaging source code, server backups, or container layers. Converting ZIP to TAR gives you a clean tarball you can pipe straight into tar, gzip, xz, pax, or a Dockerfile ADD directive without re-bundling on the destination machine.

• Linux server deployments — Most provisioning scripts, Ansible roles, and make install targets expect a .tar or .tar.gz payload. Shipping a ZIP forces an extra unzip && tar -cf round trip on the server.
• Pipe into compressors of your choice — A bare TAR lets you pick the compressor at deploy time: gzip for fast/universal, bzip2 for older Linux distros, xz or zstd for the smallest size. ZIP locks you into DEFLATE.
• Preserve the streaming property — TAR is sequential and stream-friendly; you can pipe it through SSH (tar -cf - … | ssh host 'tar -xf -') or into docker import. ZIP's central directory is at the end of the file, which breaks that pattern.
• Source distribution and pip/npm packages — sdist tarballs, autotools releases, and many language package formats are TAR-based by convention. Reviewers and mirrors expect .tar.gz, not .zip.
• CI/CD artifacts and container images — Docker layers, OCI images, Kubernetes Helm charts (.tgz), and most CI artifact stores standardize on tarballs. A ZIP usually has to be repackaged before it can be cached or shipped.
• Forensic and archival workflows — Library of Congress lists tar as a sustainable preservation format; many digital archivists prefer it over ZIP because the format is simpler, fully documented in POSIX, and doesn't depend on a per-file compression dictionary.

Frequently Asked Questions

Will the TAR file be larger than the original ZIP?

Almost always, yes. ZIP applies DEFLATE compression per file, while a plain TAR bundles raw, uncompressed data with a 512-byte header per member. Expect the output TAR to be roughly the sum of the uncompressed file sizes plus a few KB of headers. If size matters, pick a compressed tarball: ZIP to TAR.GZ usually matches or beats the original ZIP, and ZIP to TAR.XZ typically wins by 10–30% on text-heavy archives.

Does TAR preserve Unix permissions and ownership from the ZIP?

It preserves whatever the source ZIP recorded. ZIPs created by Info-ZIP, zip on Linux/macOS, or 7-Zip with the "Store Unix permissions" option include the chmod bits and UID/GID, and those carry through. ZIPs produced by Windows Explorer or older tools usually have no Unix metadata, so the output TAR falls back to default permissions (typically 644 for files and 755 for directories) under the user running tar -xf.

Can I merge several ZIP files into a single TAR?

Yes. Upload all the ZIPs and leave the Combine? option on Single Archive. The contents of every ZIP are extracted and re-packed into one TAR, with the original directory structure preserved. If two ZIPs contain a file at the same path, the later upload wins.

Why would I want an uncompressed TAR instead of TAR.GZ?

Three common reasons. (1) You're going to compress it yourself with a specific tool — xz -9, zstd --long=27, or a parallel compressor like pigz or pbzip2 — and don't want the converter's choice baked in. (2) The destination already does compression at the storage layer (ZFS, btrfs with compress=zstd, an object store with transparent gzip). (3) You're piping it directly into another process, like docker load, tar -xf -, or a build step that re-packs anyway.

Is the ustar format compatible with tar on macOS, BSD, and old Linux?

Yes. ustar (POSIX.1-1988) is the lowest-common-denominator format that every modern tar reads — GNU tar, BSD tar / bsdtar (the default on macOS and FreeBSD), and the pax utility. The output we produce sticks to ustar headers without GNU or pax extensions, so it round-trips cleanly on AIX, Solaris, and BusyBox tar as well.

Does TAR support files larger than 4 GB or paths longer than 100 characters?

ustar caps individual filenames at a 100-byte name field plus a 155-byte prefix (255 total) and individual file size at 8 GiB encoded in the octal size field. Files or paths beyond that need the GNU or pax extensions. Most archives convert without issue, but if your ZIP contains a single file over 8 GiB or a deeply nested path past 255 bytes, the conversion will fall back to GNU long-link records.

Will encrypted or password-protected ZIPs convert?

No. A ZIP that's encrypted with the legacy ZipCrypto or AES algorithms can't be read without the password, and we don't accept the password through the UI. Decrypt the ZIP locally first with 7-Zip, the macOS Archive Utility, or unzip -P, then upload the resulting plain ZIP for conversion.

How do I go the other direction — TAR back to ZIP?

Use TAR to ZIP, which decompresses the tarball (if it's .tar.gz/.tar.bz2/.tar.xz) and re-bundles the contents into a DEFLATE-compressed ZIP. You can also explore other archive targets like ZIP to 7Z for tighter compression with Windows-friendly tooling.

Are my files private during conversion?

Files are uploaded over HTTPS, processed on our server, and then deleted automatically after the session ends — typically within a few hours. We don't index, share, or open the contents. For sensitive archives we still recommend doing the conversion locally with unzip and tar (both free, both shipped with every Linux distribution and macOS install), but the online flow is fine for source code, public release artifacts, and the kinds of files you'd already email or upload to a CI runner.
