🔒 Verify the privacy claim yourself

The simplest way to confirm your files never leave this device:

Disconnect from the internet.

Turn off your Wi-Fi → the tool keeps working. The banner up top turns green.

Why this works: the tool is JavaScript + WebAssembly that runs entirely in your browser. There is no upload step. Open DevTools → Network and watch — no file ever leaves.

🔒 Verify it yourself: turn off your Wi-Fi, drop your files and start zipping. Your files never leave your device.

Why use it

🔒

Files never leave your device

All zipping and unzipping runs in your browser. No upload, no server. Disconnect from Wi-Fi mid-task — the app keeps working.

⚡

No file size cap

Drop a 5 GB folder. Drop 10,000 photos. There's no per-file or per-batch cap because we don't pay for bandwidth.

🪶

No signup, no watermark

Free forever. No account. No "click here to remove the watermark". No upsell pop-ups while you wait.

🌐

Works everywhere

Mac, Windows, Linux, iPhone, iPad, Android — any modern browser. Nothing to install.

FAQ

Do you upload my files?

No. All compression and extraction happens in your browser. You can verify by disconnecting from Wi-Fi after the page loads — the app keeps working.

What's the file size limit?

There isn't one. Your browser's memory is the only practical limit. Most desktops handle multi-GB archives without issue; mobile is more limited.

What ZIP format do you create?

Standard PKZIP / ZIP64 — opens with every operating system's built-in archive tool, 7-Zip, WinRAR, etc. We use DEFLATE compression by default.

Can I extract a password-protected ZIP?

Not yet — the current version handles unencrypted ZIPs. Password-protected ZIP support is on the roadmap.

Does this support RAR or 7z?

Not yet. This version supports ZIP only. RAR and 7z extraction is on the roadmap.
