Extract .7z Files Online

How to extract a 7z file online (free)

1. Drop your .7z file onto the box above, or click to choose it.
2. If the archive is password-protected, type the password when asked — decryption happens on your device.
3. Download files individually, grab them all, or repack everything into a .zip.

Open 7z archives without installing anything

The .7z format compresses better than ZIP, but neither Windows Explorer (before Windows 11 23H2) nor macOS Finder can open it. This extractor handles LZMA and LZMA2 — 7-Zip's default methods — via libarchive compiled to WebAssembly, so it works in any modern browser on any operating system.

AES-256 password-protected 7z files

7-Zip encrypts archives with AES-256. Drop an encrypted .7z here and the tool asks for the password, then decrypts it entirely in your browser. Nothing — not the archive, not the password — is sent to any server, which is the whole point of an encrypted archive.

Is it really private?

Yes. There is no upload step and no account. Open your browser's network tab and watch: no request carries your file data. The tool works offline once the page has loaded.

Is there a size limit?

There's no artificial cap. The archive is unpacked in memory, so the real limit is your device's available RAM — comfortable for everyday archives.
