Repackage ZIP into a compact Linux tarball

Need to send files to a Linux server or shrink an archive as much as possible? Convert your ZIP to a .tar.xz - the native Linux format with the best compression ratio.

  • Maximum compression - XZ / LZMA2 typically beats gzip and bzip2
  • All files preserved - directory structure stays intact
  • Security validated - path traversal and bomb protection built in

About Converting ZIP to TAR.XZ

ZIP is the universal archive format that bundles and compresses multiple files into one. Every operating system opens ZIP natively, making it the default for sharing file collections. When you need to move away from ZIP, the usual reason is simple: weaker compression than 7z.

Converting your ZIP archive to TAR.XZ solves that. TAR.XZ is a TAR archive compressed with XZ (LZMA2), which offers one of the highest compression ratios of any general-purpose format. It is widely used for Linux source releases and package downloads where small size matters most. In practice you gain highest compression ratio of the common tarballs and preserves unix permissions. PrivConvert runs the whole ZIP-to-TAR.XZ conversion in server memory and deletes your file the instant the TAR.XZ is ready — nothing is stored, logged or reused.

When this conversion helps

  • You need highest compression ratio of the common tarballs
  • You need preserves Unix permissions
  • You need open standard
  • Sharing a ZIP archive with someone whose software expects TAR.XZ

Tips for best results

  • TAR.XZ preserves quality exactly, so the conversion from ZIP will not introduce any new compression artifacts.
  • Files up to 250 MB are supported, and you can batch-convert several ZIP files at once; each is processed privately and deleted immediately.

Frequently Asked Questions

Why convert ZIP to TAR.XZ?
TAR.XZ is the standard on Linux and offers a much higher compression ratio than ZIP, so the same files take up less space. It's ideal for archiving or distributing content to Linux systems.
What is XZ compression?
XZ uses the LZMA2 algorithm, one of the highest-ratio general-purpose compressors available. It typically produces smaller files than gzip or bzip2.
Are folder structures preserved?
Yes. All directories and subdirectories from the ZIP are recreated inside the tarball.
Is there a file size limit?
You can upload ZIP files up to 250 MB, with a 500 MB cap on total extracted content for security.
Are my files private and secure?
Yes. Every conversion runs in an isolated process. Your files are never stored or shared and are deleted from memory the moment your download is ready.
