Why BIShare

What nothing else does at once.

AirDrop is Apple-only. Quick Share skips iPhones. LocalSend needs its app on both ends. BIShare closes all three gaps.

The recipient needs no app

Not nearby? Send a link they open in any browser to download. They install nothing, sign up for nothing — you can send a file to literally anyone.

Every platform

iPhone, Android, Windows, Mac, Linux — one app, every direction.

Private by design

Every transfer is end-to-end encrypted. Nearby, files never touch a server; by link, the relay only ever holds ciphertext. Links auto-expire in 6–24h.

Local-network speed

On the same Wi-Fi, files go directly device to device — no cloud round-trip, and no size limit at all.

Everything included

Built for the way files actually move.

Local-network speed

On the same Wi-Fi, files fly directly device to device — no cloud round-trip, no size limit.

Secure links, 6–24h

Off-network? An encrypted link up to 100 GB that works in any browser and auto-expires within a day.

Rooms

Share with a group over a short room code — everyone grabs what they need.

Scan to receive

Point a camera at the QR and the download starts. Nothing to type.

Every platform

Native apps on iOS, Android, macOS, Windows, and Linux — one experience.

No account

No sign-up, no email, no profile. Install and start sending in seconds.

How it works

Three steps. No setup.

01

Pick a device — or grab a link

Nearby devices appear automatically. Not nearby? One tap gets a link, QR, and code.

02

It's encrypted and sent

Sealed with AES-256-GCM before a byte leaves. Nearby goes straight device to device.

03

It lands, verified

Arrives intact, decrypts only on the receiving device. Links expire after 6, 12 or 24 hours.

One app. Every device.
