What happens when you convert 7Z to TAR
- Every file and folder in the 7Z is extracted in your browser and packed into a new TAR with the same structure. Nothing is uploaded.
- TAR does not compress, so the result is about the size of all the files added together.
- Password-protected archives cannot be converted, because they cannot be opened without the password.
How to convert 7Z to TAR online
- Press "Choose 7Z files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to TAR". The archive engine, about 1 MB, loads the first time; then the time depends on how much is inside the archive.
- Save each TAR with its download button. Close the tab and every trace of the files is gone from memory.
Why convert 7Z to TAR?
7Z files usually come from maximum compression for backups and software distribution. People convert them to TAR because TAR is what Linux and Mac tools, servers and build systems expect.
In short, 7Z is good at what it was made for, and TAR is the more practical choice when the file has to open, upload or print somewhere else. 7Z opens natively in Windows 11 since its 2023 update; older Windows needs 7-Zip and a Mac needs The Unarchiver, while TAR opens natively on macOS and Linux, and with tar or 7-Zip on Windows.

Best settings for 7Z to TAR
There is nothing to set: every file in the 7Z is copied into the TAR as it is.
Large archives are unpacked into your browser's memory, so very big ones, several gigabytes, are better handled by a desktop program such as 7-Zip. Archives split into several parts (.part1.rar, .part2.rar) need all parts, which this tool does not join.

About 7Z and TAR files
What is a 7Z file?
7Z usually compresses tighter than ZIP by using the LZMA algorithm across files. The trade-off is that fewer built-in tools can open it.
What is a TAR file?
A TAR file bundles files without compressing them; it keeps Unix permissions and folder structure. It is usually compressed again with gzip, giving a .tar.gz or .tgz file.
7Z to TAR not working? Common problems
- The archive will not open. It may be password protected, damaged, or one part of a multi-part archive.
- The browser tab stops on a big archive. Everything is unpacked in memory; very large archives are better handled by 7-Zip or The Unarchiver.
- Files have odd names. Archives made on some older systems store names in a local character set; the files themselves are intact.
Convert 7Z to TAR from the command line
7-Zip extracts any of these formats, and a second command packs the result:
7z x input.7z -oextracted
cd extracted && 7z a ../output.tar .The converter on this page does the same job in your browser, without installing anything.
7Z to TAR converter FAQ
Will I lose quality converting 7Z to TAR?
No. Archives are lossless: every file comes out byte for byte identical.
Why is the TAR a different size from the 7Z?
TAR does not compress, so it is usually larger than the original archive.
Are my 7Z files uploaded anywhere?
No. The conversion runs inside this browser tab using libarchive compiled to WebAssembly and the fflate ZIP library, so your files stay on your device. You can disconnect from the internet after the page and converter engine have loaded and it still works.
Can I convert several 7Z files to TAR at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a TAR file?
TAR opens natively on macOS and Linux, and with tar or 7-Zip on Windows. TAR is common for software source code and Linux and Mac backups.
Is this 7Z to TAR converter free?
Yes. There is no sign-up, no watermark and no limit on how many files you convert. The site is paid for by advertising, and because conversions run on your device there is no server cost per file.
Can I convert 7Z to TAR on my phone?
Yes. The converter works in Safari on iPhone and iPad and in Chrome on Android. Converted files are saved to the Downloads folder.
