Convert ZIP to TAR.GZ.
ZIP from Windows in, unix-ready tar.gz out — on-device.

Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
Docker contexts, CI pipelines, Linux servers and package tooling all speak tar.gz; the file you were sent is a ZIP. Drop it here and the same tree comes back as a gzipped tarball — unpacked and repacked entirely in your browser, nothing installed and nothing uploaded.
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.
Pick the right tarball compressor
gzip is the default for a reason: universal and quick. bzip2 lands a bit smaller, xz smaller still at real CPU cost — worth it for release artifacts downloaded thousands of times, overkill for a one-off transfer. The reverse direction is TAR.GZ to ZIP; building tarballs from loose files lives in the archive tool.
Frequently asked questions
Why do unix tools prefer tar.gz over ZIP?
tar predates ZIP and is woven into unix workflows — it streams, it concatenates, it preserves permissions and it compresses as one solid stream, which squeezes source trees tighter than per-file ZIP deflate. When a Makefile or a server script expects a tarball, handing it a ZIP just adds friction.
Are file permissions restored in the tarball?
Files arrive with standard default permissions — a ZIP made on Windows never contained unix modes to begin with, so there is nothing to restore. For executables, run chmod +x after unpacking on the target machine.
Can I pick tar.bz2 or tar.xz instead?
Yes — this page presets tar.gz, and the format pills switch to TAR.BZ2, TAR.XZ or plain TAR before you convert. xz compresses smallest, gzip stays the fastest and most compatible.
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.
