About HavenZip
HavenZip is a free, privacy-first archive tool that runs entirely in your browser.
Why HavenZip exists
Most online archive tools upload your files to a server to process them. We think that is unnecessary and risky. HavenZip does everything on your device, so your files stay private by design — not just by promise.
How it works
HavenZip runs real archive engines (libarchive and 7-Zip) directly in your browser through WebAssembly. Open RAR, ZIP, 7z, TAR.GZ, GZIP, XZ, ISO and more; create ZIP, 7z and TAR.GZ with optional AES-256 passwords; convert between formats; and batch-process many archives — all locally, all fast.
Free, no account, no install
There is nothing to install and no account to create. HavenZip is free and works in any modern browser. It is also an installable progressive web app (PWA) that keeps working offline.
Open and honest
We are transparent about what HavenZip does. Your files never leave your device — and you can verify it. RAR is extract-only, because it is a proprietary format we will not reverse-engineer to create.
