Frequently asked questions
How do I open a .7z file without installing 7-Zip?
Drop it here — the page runs 7-Zip itself (compiled to WebAssembly) in your browser, so every 7Z feature is supported.
What about .7z.001, .7z.002 files?
These are parts of one split archive. Select all of them together and drop them at once.
Can it open password-protected archives?
Yes — you are asked for the password, including 7Z archives with encrypted file names and AES-256 ZIP files. The password stays in your browser.
Can I convert 7Z to ZIP?
Yes — open the archive, choose ZIP under Convert and click Convert.
Are my files uploaded?
No. Everything happens in your browser with a WebAssembly build of 7-Zip — your files never leave your device, so it is safe for private and work documents. It even works offline once the page has loaded.
