Repackage 7Z Archive as TAR
Slower compression and decompression than ZIP, and no native OS support — requires 7-Zip or compatible tools. Converting to TAR gives you a key advantage: preserves unix file metadata (permissions, ownership, symlinks, timestamps) that zip silently strips. TAR is best for bundling files and directories into a single archive while preserving unix file permissions and ownership.
Why Convert 7Z to TAR?
Slower compression and decompression than ZIP, and no native OS support — requires 7-Zip or compatible tools — converting to TAR overcomes this by providing preserves unix file metadata (permissions, ownership, symlinks, timestamps) that zip silently strips
TAR is the right choice when you need to: packaging linux/unix software distributions and source code releases
Gain broader compatibility — TAR works with Unix/Linux/macOS (native), Windows via 7-Zip, Git, and WSL; fundamental to every Unix system
Your 7Z files were created for distributing large software packages where download size is critical, but now you need a format suited to different workflows
7Z vs TAR — Format Comparison
7-Zip Archive (.7z)
Tape Archive (.tar)
How to Convert 7Z to TAR
Upload your 7Z file
Drag your .7z file onto the upload area or click to browse. We accept 7Z files up to 2 GB.
Choose TAR as output format
Select .tar (Tape Archive) from the format list. Configure any format-specific settings to match your requirements.
Convert and download
Click Convert and wait for processing. Your TAR file will be ready to download in seconds. The result is optimized for bundling files and directories into a single archive while preserving unix file permissions and ownership.
Frequently Asked Questions
Is the 7Z to TAR conversion lossless?
expand_more
When both formats support lossless data, the conversion preserves all content. Exact file preservation including permissions, ownership, symlinks, and extended attributes.
How large will my TAR file be compared to the original 7Z?
expand_more
7Z files are typically 1 KB – unlimited, while TAR files are typically 1 KB – unlimited (uncompressed). The actual size depends on content complexity and any quality settings you choose.
What software can open the converted TAR file?
expand_more
TAR is compatible with: Unix/Linux/macOS (native), Windows via 7-Zip, Git, and WSL; fundamental to every Unix system.
What is the maximum file size I can convert?
expand_more
PureConverter accepts 7Z files up to 2 GB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between 7Z and TAR?
expand_more
7Z (7-Zip Archive) is best for achieving the highest compression ratios for archiving large collections of similar files. TAR (Tape Archive) is best for bundling files and directories into a single archive while preserving unix file permissions and ownership. Key tradeoff: 7Z's advantage is lzma2 compression achieves 30–70% better ratios than zip's deflate, especially on text and code archives, while TAR's advantage is preserves unix file metadata (permissions, ownership, symlinks, timestamps) that zip silently strips.
Pro Tips for 7Z to TAR Conversion
Review the output TAR file to ensure all formatting and content transferred correctly from your 7Z source
Keep a backup of your original 7Z file — while our conversion is reliable, having the source is always recommended
TAR works especially well for: backing up entire directory trees with preserved permissions for system migration
Did you know? TAR was literally designed for magnetic tape drives in 1979 — the name "Tape Archive" reflects its origin, and the sequential file layout matches how data is written to tape (no random access possible).
