What is a 7Z file?

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.

Good to know

  • 7Z files larger than 200 MB are too big to open in your browser. They are opened on our server instead, and you get everything inside as one ZIP.
  • Symbolic links, hard links and special files (such as devices) are left out for safety.

Frequently asked questions

How do I open a 7Z file?

Drop it on this page: you see every file and folder inside right away, and can save the ones you need. Nothing is installed, and the file stays on your device.

Can I save just one file from a 7Z?

Yes. Click Save next to the file. To save several, tick them (or whole folders) and click Download selected as ZIP.

Are my 7Z files uploaded anywhere?

Archives up to 200 MB never leave your device: ConvertKitty runs 7-Zip inside your browser to list and unpack them. Larger archives, and formats your browser can't open, are sent over an encrypted connection, made into one ZIP, and deleted 72 hours later. The button says "Upload and extract" whenever that happens.

Can I open a password-protected 7Z file?

Yes. The page asks for the password, and the files you save are not password-protected.

Is extracting 7Z files free?

Yes. Opening archives in your browser and saving the files is free, with no account and no limit. Archives opened on our server use credits: everyone gets 25 free credits a day, and most archives cost a single one. Credits reset at midnight UTC.

How large can the 7Z file be?

Up to 200 MB in your browser. Larger 7Z files, up to 1 GB, are opened on our server and come back as one ZIP.

Does it work on my phone?

Yes. It works in any modern web browser, on a computer or a phone, and the files you save go to your downloads.
