TAR.XZ to RAR Converter

How to Convert TAR.XZ to RAR Online

1. Upload Your TAR.XZ File: Drag and drop or click "+ Add Files" to load one or more .tar.xz archives from your device. Batch is supported — drop several .tar.xz files at once.
2. Pick a Combine Mode: Default is Single Archive, which merges the contents of every uploaded .tar.xz into one consolidated .rar. Switch to Individual Archives to produce one .rar per input archive (useful when each .tar.xz is a separate deliverable you want to keep apart).
3. Confirm Output is RAR: RAR is locked as the target extension on this page. If you'd rather keep open-format tooling, try TAR.XZ to 7z or TAR.XZ to ZIP instead.
4. Convert and Download: Click Convert. The server runs xz decompression, untars the payload, and re-packs the file tree into RAR. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert TAR.XZ to RAR?

.tar.xz is the modern Linux default — tar bundles a directory tree into a single stream, and xz (LZMA2) wraps it in tight, lossless compression. The format took over from .tar.gz and .tar.bz2 as distros moved to it for package and source tarballs through the early 2010s; Arch Linux switched packages to xz in March 2010. RAR is a separate world: a proprietary archive format created by Eugene Roshal in 1993, licensed today by win.rar GmbH, with features Linux-native formats don't offer out of the box. Converting .tar.xz to .rar re-packs the same files so they're usable in a Windows-centric, recovery-aware workflow.

• Send Linux source trees to Windows recipients without WSL — A .tar.xz from a kernel mirror or a GitHub source release won't open in Windows Explorer's built-in extractor. Re-packing it as RAR (or ZIP) means anyone with WinRAR, 7-Zip, or NanaZip on Windows can double-click straight into the tree.
• Add a recovery record before long-term storage — RAR 5 can embed an optional recovery record (typically 1-10% of archive size) that lets WinRAR repair an archive after partial corruption from a bad sector, flaky USB stick, or cosmic-ray bit flip on cold storage. .tar.xz has integrity checks (CRC32/CRC64/SHA-256) that detect damage but can't repair it.
• Multi-volume splits that survive transport limits — RAR natively splits an archive into numbered parts (backup.part01.rar, backup.part02.rar, …) at any size you choose, which is the cleanest way to email a large dataset across providers that cap attachments at 25 MB (Gmail) or move files onto FAT32 thumb drives capped at 4 GB per file. .tar.xz has no built-in split format; users typically resort to split and cat on the command line.
• Lock filenames as well as content with AES-256 — RAR 5 supports AES-256 encryption with optional filename-list encryption, so a password-protected RAR doesn't even expose the entry list. .tar.xz itself has no encryption layer at all — the usual workflow is to wrap it in gpg separately.
• Windows-shop compatibility for backups and deliverables — Procurement portals, vendor file drops, and many corporate IT environments expect .rar or .zip rather than .tar.xz. Re-packing is faster than asking the recipient to install xz tooling.
• Audit trail after the xz backdoor scare — After the CVE-2024-3094 xz-utils backdoor was disclosed in March 2024, some teams added a re-archive step in their pipeline to break any embedded reproducibility tie to specific xz builds. Re-packing into RAR is one way to do that on the storage side.

Frequently Asked Questions

Will the resulting RAR be smaller than the source .tar.xz?

Usually not by much, and sometimes it will be slightly larger. Both formats sit near the practical floor for general-purpose lossless compression on a given input — xz with LZMA2 and RAR 5 are within a few percent of each other on most data, with the winner depending on file mix. Where RAR can pull ahead is text-heavy or source-code trees in solid mode; xz often wins on already-compressed media. Convert for compatibility, recovery records, or multi-volume splitting — not to chase size savings.

Why does the conversion take a moment instead of being instant?

.tar.xz and .rar use completely different compression engines (LZMA2 vs RAR's LZSS/PPMd-style modes), so a converter has to fully decompress the xz stream, untar the payload to recover the file tree, then re-pack everything with RAR's algorithm. A "fast" tool that only rewrote the container would not give you any of RAR's recovery, encryption, or split-volume benefits — and it isn't possible at the byte level, because RAR needs to see the file boundaries that tar packs into the stream.

Can the recipient open RAR on macOS or Linux without paying for WinRAR?

Yes, for extraction. macOS users install The Unarchiver or Keka (both free on the Mac App Store) or run brew install rar. Linux users install unrar, unrar-free, or 7z (p7zip-full) from their distro. What's licensed is creating RAR — that requires a WinRAR license. RARLAB ships the UnRAR source code under a permissive license that lets any software unpack RAR, but the same license forbids using it to build a RAR-compatible creator.

What happens to Unix file permissions, symlinks, and ownership inside the tarball?

tar records POSIX file permissions, owner UID/GID, and symlinks. RAR 5 can preserve POSIX permissions and symlinks, but ownership UID/GID is a tar-specific concept — recipients on Windows will see the file tree without those attributes. If you need a perfect bit-for-bit round trip of a Linux directory, keep the original .tar.xz; if you just need the files in a Windows-friendly container, RAR is fine. Executable bits on shell scripts are preserved by most modern RAR tools when extracting onto Linux or macOS.

Is RAR 5 the same as the older RAR4 format?

No. RAR 5 (introduced with WinRAR 5.0 in April 2013) uses a new on-disk format with AES-256 encryption, BLAKE2sp checksums, dictionaries up to 64 GB, and a redesigned recovery record. RAR 4 used AES-128 and weaker integrity. Most modern extractors (WinRAR 5+, 7-Zip 15.06+, The Unarchiver 4+, recent unrar) handle both. Our converter outputs RAR with current defaults — recipients on pre-2013 tools may not be able to read it.

Should I use RAR, 7z, or just keep .tar.xz?

Keep .tar.xz if your recipient is on Linux or your build pipeline is on Linux — it's the native format, integrates with tar flags (--xattrs, --acls), and tools like pixz parallelise it well. Switch to 7z if you want the best raw compression and an open format that Windows users can also extract with 7-Zip or NanaZip. Switch to RAR when you specifically want recovery records, native multi-volume splits, or you're sending into a Windows-centric workflow where RAR is the local norm. For maximum universal openability, ZIP is the safest bet — every modern OS extracts it natively.

Does this preserve nested archives (e.g., a .tar inside the .tar.xz)?

Yes. The converter decompresses only the outer .xz layer and unpacks the tar stream once. Anything inside that — including nested tarballs, zip files, jar files, or .deb/.rpm packages — is treated as opaque bytes and re-packed verbatim into the RAR. The recipient extracts the RAR and gets the same nested structure they would have gotten from tar -xJf on the original.

What's the reverse direction?

Use convert RAR to TAR.XZ when you're pulling files from a Windows-origin RAR into a Linux backup or build pipeline. If you only need to pull individual files out without re-archiving, Extract RAR and Extract TAR.XZ are the dedicated unpackers.

Is anything uploaded to your servers?

Archive conversion runs server-side because xz decompression and RAR encoding are CPU-intensive and not currently practical in-browser at scale, but uploads are processed within your session and removed afterwards. No account is required and there are no watermarks, file-count limits, or hidden Pro tiers gating this conversion.
