Zip & unzip files online
Drop an archive to open it
ZIP, RAR, 7z, TAR, GZ and more — or click to browse. Everything stays on your device.
How it works
-
Drop an archive to open it — or drop the files you want to zip up.
-
The tool detects the format automatically and reads or bundles it.
-
Extract: save the whole folder or download files. Compress: pick ZIP or 7z.
-
Everything runs on your device — nothing is uploaded.
How it works
Extraction is handled by libarchive compiled to WebAssembly, which reads ZIP, RAR, 7z and the TAR family right in your browser. New ZIP archives are built with a pure-JavaScript encoder, and 7z archives use the real 7-Zip engine compiled to WebAssembly. There's no server and no upload — your files are read and written on your device, so nothing is transmitted or stored anywhere.
Frequently asked
Is this zip/unzip tool really free, and are my files uploaded?
It's completely free, with no signup and no watermark. Nothing is uploaded — extraction and compression run entirely in your browser using WebAssembly, so your files never leave your device.
Which archive formats can I open?
You can extract ZIP, RAR (both RAR4 and RAR5), 7z, TAR, GZ, TAR.GZ, BZ2 and XZ. Just drop the file — the tool detects the format automatically, so you never have to pick one.
Can I create archives too?
Yes. Drop the files you want to bundle and choose ZIP or 7z. Creating RAR isn't possible in any browser — the RAR format is proprietary and can only be read, not written — so we support the two open formats instead.
Can it open password-protected archives?
Yes. If an archive is encrypted, the tool asks for the password and then extracts it locally. (Creating password-protected archives isn't supported yet.)
Does it work on a Mac, Chromebook, or iPad?
Yes — there's nothing to install. Any device with a modern browser works. On Chrome and Edge you can save the whole extracted folder in one click; other browsers download the files individually.
Is there a file-size limit?
There's no server limit because nothing is uploaded. The practical ceiling is your device's memory, since the archive is processed in the browser. Very large archives may be slow or run out of memory.
