Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
Bundle files into a .tar.xz entirely in your browser — the tightest mainstream tarball format, built locally with nothing uploaded. The packaging Linux distributions and software releases standardized on, one drag-and-drop away.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- Compress, compare before/after, and download — individually or as a ZIP.
Maximum squeeze, understood trade-offs
xz (LZMA2) typically undercuts gzip by 25–40% on compressible payloads, which is why release artifacts ship as .tar.xz — built once, downloaded many times. The price is CPU: creation is the slowest of the family, so patience on big trees is normal. Create TAR.GZ wins when speed or maximum compatibility matters, and Create 7Z offers the same LZMA family plus AES-256 encryption.
What ships as .tar.xz
The format earned its place at the top of the food chain — where a file is built once and downloaded millions of times, the extra build minutes buy real bandwidth:
| Ecosystem | Why xz |
|---|---|
| kernel.org | Linux kernel sources ship as .tar.xz — bandwidth at that scale is money |
| GNU and GNOME releases | The project standard for source tarballs |
| Debian source packages | orig tarballs moved from gz to xz years ago |
| Slackware packages | The distribution’s .txz package is a tar.xz by another name |
Frequently asked questions
How much smaller than tar.gz?
Typically 25–40% on source code, text and mixed payloads. Already-compressed content (media, existing archives) barely budges in any format.
Why does creating it take so long?
xz trades CPU for ratio by design — it searches much harder for redundancy than gzip. The decompress side is fast; only creation is slow.
Who can open .tar.xz?
Every modern unix out of the box, and 7-Zip or PeaZip on Windows. For non-technical recipients, ZIP remains the safer handoff.
Is it private?
Yes. Archives are built and converted entirely in your browser — neither the archive nor the files inside it are ever uploaded, and any password you set is applied locally. The server does nothing but deliver this page. Want proof? Run one file through, switch your connection off, and run another — it still works.
