Add multiple files or keep a folder's relative paths.
7Z protects file contents and hides filenames.
Processing takes place in this browser tab. Files are not uploaded by this tool.
The 7Z format is designed for efficient archiving and is a practical option for backups, source bundles, asset packages, and collections that will be opened with a compatible archive manager. Multiple files and nested folder paths can be stored in one .7z file.
Smaller output is not guaranteed because many media files and installers are already compressed. The browser also needs enough working memory for the selected files, so very large collections are better divided into manageable parts.
7Z is useful when compact storage is important and recipients have software that can open it. ZIP is usually easier for recipients who rely only on built-in phone or desktop tools.
Yes. Select Folder keeps the relative directory structure, including nested folders, in the resulting .7z file where the browser supplies those paths.
The selected files remain on your device while the archive is created. The downloaded 7Z file is generated in the current browser tab.
Yes. Enter a password before compression to protect the file contents and hide the filenames stored in the 7Z archive. The same password is required to open it.
A 7Z-compatible archive manager is required. Many dedicated archive apps support it, but some operating systems and mobile file managers do not open 7Z files by default.
