TAR.GZ Converter

How to Convert TAR.GZ to Any Format

1. Upload Your TAR.GZ File: Drag and drop your archive or click "Add Files". The tool accepts .tar.gz and its short form .tgz — they are the same format. Drop in several archives and each one converts in its own job.
2. Pick an Output Format: Choose the target archive — ZIP, 7Z, TAR, RAR, TAR.XZ, TAR.BZ2, or TGZ. ZIP is selected by default because it opens with a double-click on Windows, macOS, and Linux without extra software.
3. Choose Single or Individual Archives: When you upload more than one file, "Individual Archives" produces one output per input (the default for archive-to-archive jobs), while "Single Archive" repacks everything into one combined archive.
4. Convert and Download: Click Convert. 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.

Popular TAR.GZ Conversions

• TAR.GZ to ZIP — the most common target, so Windows and macOS users can open it with a double-click, no 7-Zip or WinRAR needed
• TAR.GZ to 7Z — repack into 7-Zip's LZMA2 format for a noticeably smaller archive
• TAR.GZ to TAR.XZ — keep the Unix tar layout but swap gzip for xz, which compresses tighter
• TAR.GZ to TAR — strip the gzip compression to get the plain uncompressed tarball
• TAR.GZ to TAR.BZ2 — re-compress with bzip2, common on older Linux mirrors
• TAR.GZ to RAR — repack into a RAR archive for WinRAR-based workflows

Why Convert a TAR.GZ File?

TAR.GZ — also written .tgz — is a TAR bundle (the Unix tape-archive format, introduced to Unix in January 1979) that has then been compressed with gzip. Gzip uses the DEFLATE algorithm defined in RFC 1952 (May 1996), the same algorithm ZIP uses internally. The result is the de-facto distribution archive of the Unix and Linux world: source tarballs, server backups, container layers, and software releases ship as TAR.GZ because it preserves Unix file permissions and ownership and decompresses fast on any Unix-like system.

The friction shows up the moment a TAR.GZ leaves that world. Reasons people convert it:

• Opening it on Windows or macOS — Neither has a native double-click handler for .tar.gz the way both do for ZIP. Converting to ZIP lets a non-technical recipient open the archive with built-in tools, no 7-Zip or WinRAR install required.
• Shrinking the archive — Gzip is fast but is the weakest of the common tar compressors on ratio. Re-compressing to 7Z (LZMA2) or TAR.XZ (LZMA) typically yields a smaller file for the same contents, which matters for long-term backups and large source trees.
• Stripping compression for re-processing — A build pipeline or indexer sometimes wants the raw TAR so it can apply its own compression, or simply to inspect the contents without a gzip step.
• Matching a mirror's convention — Some package mirrors and legacy projects still distribute as .tar.bz2; converting to TAR.BZ2 matches that house style.

A conversion here is a full repack, not a rename: the tarball is decompressed, the file tree is read, and the files are written into the new container with the new compressor. The bytes inside your files are unchanged — archive conversion is lossless regardless of which format you pick.

TAR.GZ vs Its Common Targets

Frequently Asked Questions

Is .tgz the same as .tar.gz?

Yes. .tgz is just the short, single-extension spelling of .tar.gz — both name a TAR bundle compressed with gzip, with identical bytes inside. The short form exists mostly because older filesystems (and some Windows tooling) preferred a single three-letter extension. This converter accepts either spelling and treats them the same, and converting "TAR.GZ to TGZ" simply renames the wrapper rather than re-compressing.

What opens a TAR.GZ file?

On Linux and macOS, tar -xzf archive.tar.gz in a terminal extracts it, and most Linux desktop archive managers open it on double-click. Windows 11 added native tar command-line support and, more recently, GUI extraction of tar-based archives, but for a non-technical recipient the safest path is still to convert TAR.GZ to ZIP, which every version of Windows and macOS opens with a double-click using built-in tools.

Should I convert TAR.GZ to 7Z or TAR.XZ for a smaller file?

Both shrink it more than gzip, with a tradeoff. 7Z (LZMA2) usually produces the smallest archive of the common formats, but the recipient needs 7-Zip to open it. TAR.XZ (xz/LZMA) compresses tighter than gzip while keeping the familiar Unix tar layout, so it is the natural choice when you are staying in a Linux or distro-packaging context. If the recipient's toolset is unknown, 7Z gives the best size; if they live on Unix, TAR.XZ keeps things native.

Will converting TAR.GZ to another archive change the files inside?

No. Archive conversion is lossless — the converter decompresses the tarball, reads the exact file tree, and re-writes it into the new container. Your documents, code, and binaries come out byte-for-byte identical. The only thing that changes is the compression algorithm wrapping them, which affects file size and which program can open the archive, not the contents.

Does converting TAR.GZ to ZIP keep Unix file permissions?

Partly. TAR is designed to store full Unix permissions and ownership, and ZIP can record Unix permission bits in its extra fields, but support varies by extractor — Windows Explorer ignores those bits entirely when unzipping. If preserving exact permissions and ownership matters (for example restoring a server backup), keep the archive in a tar-based format like TAR or TAR.XZ rather than ZIP.

How big a TAR.GZ can I convert, and is it private?

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 or made public. There is no fixed per-file cap; the practical limit is your upload size and connection speed, so multi-gigabyte backups are fine if you can upload them. In our testing, a 180 MB .tar.gz of mixed source files re-packed to ZIP in well under a minute, with the output landing close to the original size since both formats use DEFLATE.
