What is a RAR file?
RAR – RAR archive. RAR is a proprietary archive format from RarLab, popular for large downloads because of its strong compression and recovery records. Opening it is free; creating it needs the licensed WinRAR tools.

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 RAR 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 RAR 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.
Can I convert a password-protected RAR file?
Yes. Click Options next to the file and enter its password. The 7Z you get back is not password-protected.
How large can the RAR 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 RAR be kept?
Yes. The 7Z has the same folders and file names as the RAR. Only links and special files are left out, and the page tells you if it did that.
Can I convert several RAR 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.
