What quality should I expect from the TAR.GZ output?

Our converter preserves as much fidelity as Gzipped Tar Archive allows. Where 7-Zip Archive carries information that Gzipped Tar Archive cannot represent, that information is mapped to the closest equivalent (for example, color spaces, codec parameters, or metadata fields). For most everyday uses the result is indistinguishable from the source.

Are my filenames, folder structure, and timestamps preserved in the TAR.GZ archive?

Yes. The directory structure, filenames (including Unicode characters), and modification timestamps are carried over from your 7-Zip Archive archive into the Gzipped Tar Archive output. File permissions are preserved when both formats support them. The result is a functionally equivalent archive — just in a different container, ready to extract on systems that prefer TAR.GZ.

What file size should I expect for the TAR.GZ output?

The output size depends on the content and the compression characteristics of Gzipped Tar Archive. In most cases the TAR.GZ file will be in the same ballpark as your 7Z input, with differences driven by how each format encodes data. There is no fixed ratio — the converter does not change quality settings unless you ask it to.

When should I convert 7Z to TAR.GZ instead of staying with 7Z?

Convert when the application, device, or workflow you are targeting prefers Gzipped Tar Archive over 7-Zip Archive. If your current 7Z file already opens and behaves correctly everywhere you need it to, there is no benefit to converting — keep the original. The most common reasons to switch are compatibility (a tool only accepts TAR.GZ), distribution (recipients expect TAR.GZ), or feature requirements specific to Gzipped Tar Archive.

What is the maximum 7Z file size I can convert?

MegaConvert accepts 7Z files up to 100 MB on the free service, which is enough for the vast majority of real-world 7-Zip Archive files. If you have a larger file (typical for high-resolution video or uncompressed audio), please contact us — we can sometimes accommodate larger uploads for legitimate use cases.

Is my 7Z file safe and private when I upload it?

Yes. Your 7Z file is uploaded over HTTPS, processed in an isolated job environment, and deleted from our servers within one hour. We do not read, index, store, or share the contents of your file. No account is required, so the upload is not associated with a personal identity. See our privacy policy for the full details.

Why Convert 7Z to TAR.GZ?

Understand when and why this conversion makes sense for your workflow.

Converting 7-Zip Archive to Gzipped Tar Archive helps resolve compatibility issues when sharing compressed files across different operating systems and software environments. Archive formats vary in their compression algorithms, split archive support, password protection, and native tool availability. What opens effortlessly on one system may require third-party software on another, making format conversion an important step when collaborating across platforms.

7-Zip Archive has a known limitation: not natively supported by operating systems; requires 7-Zip or compatible software. In contrast, Gzipped Tar Archive offers a key advantage: standard archive format on Unix/Linux with universal tool support. While 7-Zip Archive is commonly used for maximum compression for large file distribution and archival, Gzipped Tar Archive is better suited for linux and unix source code and software distribution.

MegaConvert repackages your 7Z archive into TAR.GZ format reliably, ensuring recipients on any platform can extract the contents without compatibility issues.

How to Convert 7Z to TAR.GZ

Follow these simple steps to convert your file in seconds.

Upload your 7Z archive
Drop your .7z file or browse to select it. Archives up to 100 MB are supported — that is the size of the archive itself, not the size of its contents after extraction. Password-protected archives cannot be repackaged unless the password is supplied alongside the upload.
Click "Convert to TAR.GZ"
Start the conversion. We extract the contents of your 7-Zip Archive archive into temporary storage, then re-pack everything into Gzipped Tar Archive using sensible compression defaults. Folder structure, filenames, and timestamps are preserved.
Wait for the conversion to complete
The conversion usually takes just a few seconds. The progress bar updates in real time while your 7-Zip Archive file is processed and the new Gzipped Tar Archive file is generated.
Download your .tar.gz file
When the conversion finishes, click the download link to save the new Gzipped Tar Archive file to your computer. The file is yours — no watermarks, no expiration on the file itself, and no MegaConvert account is required to download it.

Tips for Converting 7Z to TAR.GZ

Practical advice to get the best results from this conversion.

Why this conversion is worth doing

7-Zip Archive has a known limitation: not natively supported by operating systems; requires 7-Zip or compatible software. Gzipped Tar Archive addresses this with a key advantage: standard archive format on Unix/Linux with universal tool support. Converting from 7Z to TAR.GZ is most worthwhile when this specific trade-off matters for the way you intend to use the file.

Match the format to the actual workflow

7-Zip Archive is most commonly used for maximum compression for large file distribution and archival, while Gzipped Tar Archive is the standard for linux and unix source code and software distribution. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where 7Z is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.

Watch for this limitation in the TAR.GZ output

Gzipped Tar Archive has its own limitation worth understanding before you commit: cannot extract individual files without decompressing the entire archive. After the conversion completes, open the TAR.GZ file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.

Check native tool availability for your target format

ZIP is natively supported on Windows, macOS, and Linux without any additional software. 7Z offers better compression but requires 7-Zip or equivalent software. RAR requires WinRAR or a compatible extractor. If you're sharing with non-technical users, ZIP is the safest format to maximize compatibility.

Understanding 7Z and TAR.GZ Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

7-Zip Archive

application/x-7z-compressed

7z is an archive format developed by Igor Pavlov for the 7-Zip archiver, using LZMA and LZMA2 compression algorithms by default. It supports multiple compression methods, solid compression (compressing multiple files as a single data stream), AES-256 encryption, and very large file sizes. 7z typically achieves 30-70% better compression than ZIP for similar content.

Advantages

Excellent compression ratios, typically 30-70% better than ZIP
Strong AES-256 encryption for archive and filename protection
Solid compression mode further improves ratios for similar files

Limitations

Not natively supported by operating systems; requires 7-Zip or compatible software
Slow compression speed compared to ZIP, especially at high settings
No preservation of Unix file permissions in standard implementations

Common Uses

Maximum compression for large file distribution and archival
Encrypted file storage and secure file sharing
Software distribution where download size is critical

Target Format

Gzipped Tar Archive

application/gzip

TAR.GZ (also written as .tgz) combines the TAR archival format with gzip compression, creating a compressed archive of multiple files and directories. This two-step process first bundles files into a TAR archive preserving Unix permissions and structure, then compresses the result with gzip. TAR.GZ is the most common archive format on Unix and Linux systems.

Advantages

Standard archive format on Unix/Linux with universal tool support
Preserves Unix file permissions, ownership, and symbolic links
Good balance of compression speed and ratio for general use

Limitations

Cannot extract individual files without decompressing the entire archive
Less efficient compression than tar.bz2 or tar.xz
Not natively supported in Windows without third-party tools

Common Uses

Linux and Unix source code and software distribution
System administration backup archives
Open-source project release packaging
