--- title: "Extract 7Z Online — Unpack 7-Zip Archives | Compress Pro" description: "Unpack .7z archives in your browser — no 7-Zip install needed, nothing uploaded. Password-protected and header-encrypted archives both supported." canonical: https://compress-pro.com/extract-7z --- # Extract 7Z archives. > Unpack 7Z archives locally — every file its own download. A .7z on a machine without 7-Zip is a locked box. This page is the key: drop the archive and each file inside becomes its own download, **decompressed entirely in your browser** — LZMA2, encrypted archives, even ones whose file list is hidden behind the password. **No uploads · No ads · Free & open source.** ## How it works 1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V. 2. Pick a quality or preset — or set an exact target size and let the tool find it. 3. Compress, compare before/after, and download — individually or as a ZIP. ## Loose files or a friendlier archive Need the contents once? Extract here and grab the files. Passing the archive along? [7Z to ZIP](https://compress-pro.com/7z-to-zip) rebuilds it as a ZIP anyone can open, and [Create 7Z](https://compress-pro.com/create-7z) makes fresh 7Z archives — with AES-256 if you set a password. ## Frequently asked questions ### Do encrypted 7Z archives open? Yes — both flavors. Data-encrypted archives list their contents and ask the password to extract; header-encrypted ones (-mhe) reveal nothing until the password is right. Either way decryption happens locally. ### Why do people ship 7Z instead of ZIP anyway? Compression. On text, code and databases 7Z routinely lands 20-40% smaller than ZIP — worth the compatibility tax inside teams that all run 7-Zip. This page removes that tax for everyone else. ### Can I turn the 7Z into a ZIP instead of loose files? Yes — the 7Z to ZIP converter repacks the whole archive in one step, folders intact, so you get a single file that opens everywhere instead of individual downloads. ### Is it private? Yes. The archive is opened and unpacked on your own device — its contents are never uploaded, and a password, if one is needed, is used locally and never transmitted. The server does nothing but deliver this page. Want proof? Run one file through, switch your connection off, and run another — it still works. ## Related tools - [Convert 7Z to ZIP](https://compress-pro.com/7z-to-zip) - [Create 7Z archives](https://compress-pro.com/create-7z) - [Extract RAR archives](https://compress-pro.com/extract-rar) --- Part of [Compress Pro](https://compress-pro.com/) — every tool page has a markdown twin at `.md`.
