What is a TAR file?
TAR – Tape archive. TAR bundles files and folders into one archive without compressing them, keeping Unix permissions and timestamps. It is usually paired with a compressor such as gzip or xz.

7Z – 7-Zip archive. 7Z is the native format of the open-source 7-Zip. It packs files tighter than ZIP, mostly thanks to LZMA2 compression, and supports AES-256 encryption of both contents and file names.

Frequently asked questions
Is converting TAR to 7Z free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my TAR files uploaded anywhere?
Files up to 200 MB never leave your device: ConvertKitty runs 7-Zip inside your browser. Only larger files, or formats your browser cannot handle, are sent to our server, over an encrypted connection, and deleted 72 hours after the conversion. The button says "Upload and convert" whenever that happens.
How large can the TAR file be?
Files up to 200 MB are converted right in your browser. Larger files, up to 1 GB, are converted on our server.
Will the folders inside my TAR be kept?
Yes. The 7Z has the same folders and file names as the TAR. Only links and special files are left out, and the page tells you if it did that.
Can I convert several TAR files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
