Z to 7Z Converter

Convert Z files to 7Z. Free and without uploading.

This tool converts Z files to 7Z. Unix compress file.

7Z is 7-Zip’s archive format. It usually compresses better than ZIP and supports strong AES-256 encryption, but most systems need extra software to open it. The Z archive is opened and its files and folders are repacked as 7Z. For password-protected archives you can enter the password, and set one for the new archive too.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your Z files, paste them, fetch one from a link, or use "Choose files".
2. Enter the password if the archive has one.
3. Press "Convert" and download the 7Z files.
