Extract 7Z archives.
Unpack 7Z archives locally — every file its own download.

Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
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.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- 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 rebuilds it as a ZIP anyone can open, and 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.
