🔒 End-to-end encrypted☁️ Nothing uploaded to the cloud⚡ Full-speed LAN direct🌐 Works in any browser

Every file-sharing annoyance, solved in one place

Every design choice targets a real pain point

Pain 01
Chat apps compress your videos and gate large files behind VIP
FlashSend: peer-to-peer transfer of the original file — no compression, no renaming, no format limits. What arrives is exactly what was sent.
Pain 02
iPhone to Android or phone to PC means cables and extra apps
FlashSend: both ends just open a browser and scan. iOS, Android, Windows, macOS, Linux — if it has a browser, it works.
Pain 03
Cloud drives upload first, share later — gigabytes of waiting
FlashSend: in direct mode you pick and send while streaming to disk. Speed is simply the bandwidth between the two devices — no "uploading 99%".
Pain 04
Afraid to sign into personal accounts on print-shop or public PCs
FlashSend: never logs into anything. Room codes are one-time and short-lived — burn after use, no privacy traces.
Pain 05
Worried your files sit on someone else's cloud server
FlashSend: file contents travel over an encrypted WebRTC channel straight to the other device. The server only helps with the handshake — it never touches your files.
Pain 06
A one-off transfer that demands registration and real-name checks
FlashSend: zero signup within the free quota. Cross-network transfers are free — an account is only needed for larger file quotas and unlimited transfers.

Core features

Small and fast — focused on making "send a file" effortless

📷

QR / room-code pairing

One side shows a QR from a new room; the other scans or types the 6-character code. The connection is typically established within seconds.

🔐

End-to-end encrypted

Encrypted WebRTC DTLS channel, with an on-screen safety code (PIN) to check against man-in-the-middle.

📦

Any format · big files

Chunked streaming with receive-side disk writes — huge videos and archives never blow up memory.

📎

Batch transfers

Drop in multiple files and they queue up; the receiver saves them one by one. GB-class files stream straight to disk.

📶

Same-network direct

On the same Wi-Fi it uses LAN host connections — fast, and no server or WAN bandwidth is consumed.

🌙

No interrupted transfers

Screen Wake Lock keeps phones awake during transfers — no lock-screen dropouts.

📲

PWA installable

Install it like a native app and open it straight from your home screen next time.

🌐

Works across networks

Devices on different Wi-Fi (e.g. phone data to home PC) can still connect; if direct fails, it falls back to an encrypted relay — free included.

FAQ

Do my files pass through your servers?

No. File contents are transferred peer-to-peer between the two devices over an encrypted channel; the server only helps with the handshake and never touches the files. When a direct link fails (e.g. across networks), it automatically falls back to an encrypted relay — and the relay stores no file content.

Do I need an account?

Not for basic free use. Cross-network transfers are free — an account is only needed for larger relay file limits and unlimited transfers (Pro). Benefits are tied to the account and work across devices.

Can the two devices be on different networks?

Yes. Cross-network works on the free plan: e.g. use phone data to reach your home PC — when a direct link fails, the system automatically switches to an encrypted relay.

How large can files be? What formats?

Any format. Free allows up to 100 MB per file; Pro allows 5 GB over relay — and P2P direct transfers aren't actually limited by that, only by the two devices and browsers. The receiver streams to disk as chunks arrive.

Can someone guess my room code?

Codes are 6-character Base32, one-time and short-lived, and expire when the room closes. After connecting, both sides can compare the on-screen safety code (PIN) to guard against man-in-the-middle swaps.

Which devices are supported?

Anything with a modern browser: iOS / Android phones, Windows / macOS / Linux computers, tablets. No app install needed — or add to home screen for an app-like experience.
