AlterSend is a fast, private file transfer app that sends files directly between your phone and computer — no cloud, no accounts, and no size limits.

Most file sharing apps upload your files to a server first. AlterSend doesn't. It connects your devices peer-to-peer and streams files straight from one device to the other, so your data never sits on someone else's cloud. Open the app, share a code or scan a QR, and start sending.

WHY ALTERSEND

🔒 Private by design — peer-to-peer and end-to-end encrypted. Files go directly between devices, never through a third-party server.
⚡ Fast, direct transfers — send large files, folders, and long videos without waiting on slow uploads.
📁 No size limits — share big videos and documents without compression or caps.
📱 Cross-platform — transfer files between Android, iPhone, Mac, and Windows.
🙅 No sign-up — no account, no email, no ads.
🔗 Simple pairing — connect with a short join code or a QR scan.

HOW IT WORKS

1. Open AlterSend on both devices.
2. Share the join code, or scan the QR code, to connect.
3. Pick your files and send — they arrive on the other device in seconds.

PRIVACY YOU CAN TRUST

AlterSend is built for people who care about privacy. There are no accounts to create and nothing to sign in to. Files transfer over an encrypted peer-to-peer connection and are never stored on our servers — because there are no servers in the middle. What you send stays between your devices.
