Create 7z
Compress your files and folders as 7z, often smaller than a ZIP. Optional AES-256 encryption, file names included.
Processed on your device — nothing is uploaded.
First use: the 7-Zip engine (1.7 MB) is downloaded once, then kept by your browser.
How to create a 7z archive
Drop your files or add a whole folder.
Choose the compression level and a password if needed.
Click Create 7Z and download the archive.
