7Z to TAR Converter
Processing entirely on your device — large files may take a moment.
7Z is the format of 7-Zip: the best compression ratios of any mainstream archiver, with AES-256 encryption, but Windows Explorer cannot open it without extra software. TAR preserves the exact file tree and permissions that Linux tooling expects.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How 7Z compares to TAR
| 7Z | TAR | |
|---|---|---|
| Compression | LZMA / LZMA2 | None (pair with gzip/zstd) |
| Encryption | AES-256 native | None |
| Bundling | Multi-file, solid mode | Unix-faithful bundling |
| Best for | Maximum compression, secure archives | Linux packaging and source trees |

About the 7Z format
7Z is the native format of Igor Pavlov's 7-Zip (1999), built around LZMA/LZMA2 compression — for years the ratio king against ZIP and RAR — with AES-256 encryption, solid archiving (similar files compress as one stream) and open, unpatented specifications. A 7Z of the same photos or code is routinely 20–40% smaller than its ZIP.
The trade-off is platform defaults: Windows Explorer and macOS Archive Utility do not open 7Z without third-party tools (7-Zip, PeaZip, Keka). It is the format for maximizing compression on your own terms, and for encrypted archives done properly (header encryption included).
+ Strengths
- ✓Top-tier compression ratio (LZMA2)
- ✓Real AES-256 encryption, optional header encryption
- ✓Open format, free tooling everywhere
! Limitations
- −No native OS support — recipients need tools
- −Solid mode makes single-file extraction costly
About the TAR format
TAR (tape archive) is Unix's fifty-year-old answer to bundling: it concatenates files with headers into a single stream, preserving POSIX permissions, ownership and symlinks — but compressing nothing. It is the container half of the classic .tar.gz pairing and the native format of Linux source trees and backups.
Being pure bundling, TAR pairs with a compressor: gzip (the classic), bzip2, zstd. Alone, a TAR is the same size as its contents. Windows 10+ ships bsdtar, so even Windows can unpack it now — permissions aside, where NTFS has no room to be faithful.
+ Strengths
- ✓Preserves Unix permissions and symlinks
- ✓Streamable: works over pipes and tapes
- ✓The standard of Linux distribution and backup
! Limitations
- −No compression by itself
- −No built-in encryption
- −Permissions meaningless on Windows filesystems
Why convert 7Z to TAR?
There is a concrete reason this conversion exists: No native OS support — recipients need tools TAR sidesteps that — Preserves Unix permissions and symlinks If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this 7Z to TAR converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for 7Z to TAR?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are the files inside my 7Z archive modified?
No. Contents are unpacked in memory and repacked into TAR byte-for-byte — the conversion changes the container, never the files inside it.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
