How to convert TAR to 7Z
Add your TAR archives
Drop TAR files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
7Z is already chosen
Press Convert. There is nothing else to set. The work happens in this tab.
Download
Save the 7Z, or download everything as one ZIP if you converted several files.
Why ToAny
Private by construction
The TAR to 7Z converter is part of this page and runs inside your browser. Your archives are never sent to ToAny or to anyone else.
No upload, no queue
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
Free, without an account
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
TAR to 7Z: what to expect
TAR is unfamiliar outside Unix and does not compress anything. 7z usually compresses tighter than ZIP. TAR is at home in bundling files on Unix systems; 7Z is the usual choice for the smallest archives.
A password-protected archive is refused, since its contents cannot be read without the password.
TAR vs 7Z
7Z
7-Zip archive
7z is the format of the open-source 7-Zip tool. It usually compresses noticeably better than ZIP, at the cost of needing an extra app on many computers.
Opens in 7-Zip, Keka, The Unarchiver, WinRAR; not built into older Windows or macOS

Questions
Are my archives uploaded anywhere?
No. The TAR to 7Z conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Is anything lost when converting TAR to 7Z?
No. The files inside are repackaged unchanged.
Can I convert several TAR files at once?
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
How do I convert TAR to 7Z on Windows, Mac, iPhone or Android?
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the TAR file, press Convert and save the 7Z. There is nothing to install.
Is there a file size limit?
Yes. An archive can be up to 500 MB, unpack to at most 1 GB and hold up to 50,000 files; beyond those limits the page says so. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
