Create Archive

Pack files and folders into ZIP (with AES-256 password), 7Z, TAR, TAR.GZ, TAR.XZ, TAR.BZ2 or TAR.ZST.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Create Archive works

Archives are opened and packed by 7-Zip compiled to WebAssembly (7z-wasm, LGPL-2.1 with the unRAR licence restriction). It is a separate engine file of about 1.6 MB that your browser downloads once and caches, and it runs in a background thread so the page stays responsive. Gzip and Zstandard layers for TAR use fflate and zstd-wasm.

Input: Any files, Folders. Output: ZIP, 7Z, TAR, TAR.GZ, TAR.XZ, TAR.BZ2, TAR.ZST.

How to use Create Archive

1. Drop files, or choose a whole folder.
2. Pick a format and compression level.
3. Optionally set a password (ZIP or 7Z).
4. Create the archive and download it.

Tips

• ZIP opens on every computer. 7Z is usually the smallest.
• With a 7Z password you can also hide the file names.

Create Archive FAQ

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
