Very secure. Zip uses WebRTC for peer-to-peer transfers, which means your files travel directly between your devices with end-to-end encryption. The connection is secured using DTLS (Datagram Transport Layer Security), and the data is encrypted using SRTP (Secure Real-time Transport Protocol). No one—not even us—can see the contents of your files.

No, never. Your files are transferred directly between devices and are never uploaded to or stored on our servers. We only facilitate the initial connection between devices—once connected, all data flows directly peer-to-peer. After the transfer completes, there's no trace of your files anywhere except on the receiving device.

The peer-to-peer connection is encrypted, making interception extremely difficult. However, for maximum security:

• Only share your session code with the intended recipient
• The code expires after one use and cannot be reused
• Use trusted networks when possible

Zip works on any device with a modern web browser that supports WebRTC:

• Desktop: Chrome, Firefox, Safari, Edge (latest versions)
• Mobile: Safari on iOS, Chrome on Android
• Tablets: iPad, Android tablets

No app installation required—just open the website in your browser.

Yes! Zip works great on both iPhone and Android devices. On iPhone, use Safari (the default browser). On Android, use Chrome for the best experience. Simply scan the QR code with your phone's camera or enter the session code manually.

No. Zip works across different networks and even across the internet. Your devices can be on different WiFi networks, or one can be on mobile data. WebRTC handles the connection automatically, finding the best path between devices.

There's no limit on individual file size—you can send files of any size. However, there are daily transfer limits based on your plan:

You can send as many files as you want, one at a time. Each transfer is a single file. The only limit is your daily data allowance (which resets every 24 hours). Pro users have unlimited transfers with no restrictions.

All file types are supported. Photos, videos, documents, PDFs, zip archives, music, code files—you name it. If your device can select it, Zip can transfer it.

The free tier includes:

• Anonymous use: 10 MB/day without creating an account
• Free account: 100 MB/day when you sign up (free)
• All security features (encryption, P2P transfer)

Creating a free account takes 30 seconds and gives you 10x more daily transfer capacity.

Yes, absolutely. You can cancel your Pro subscription at any time from your account page. When you cancel:

No questions asked, no hoops to jump through.
