FileCourier transfers files peer-to-peer, encrypted end-to-end over a direct WebRTC channel. Your file never touches any server. Up to 10 files at once, any size.
Everything you need, nothing you don't. No account, no cloud, no limits — just a link and a transfer.
Your files are never uploaded anywhere. Data streams peer-to-peer, device to device, leaving zero trace on any server.
Home WiFi, different ISPs, mobile data — FileCourier auto-adapts. STUN for direct connections, TURN relay as fallback.
Chrome and Edge stream files directly to disk — no RAM limit, no waiting. Other browsers handle up to 512 MB.
Every connection is protected by DTLS-SRTP — the same encryption standard used in secure banking and video calls.
No subscriptions, no credits, no paywalls. Open source under MIT license. Self-host it yourself if you want.
Queue up to 10 files at once. Each is offered individually — receiver accepts or declines before bytes flow.
Three steps, no account, no install. Works in any modern browser.
A unique share link is generated instantly on your device. No login, no setup.
Copy the link and send it via WhatsApp, email, SMS — anything. Add up to 10 files to the queue.
Your friend opens the link, accepts the file, and it streams directly from your device — encrypted, instant.
No analytics. No cookies. No tracking. What passes through the server is only the handshake — never your file.
File data never passes through any server. It goes directly from your browser to theirs.
WebRTC mandates DTLS encryption. No one — not even us — can read what's being transferred.
No tracking scripts, no cookies, no fingerprinting. We don't know who you are or what you sent.
Share a link. That's it. No email, no password, no personal data collected — ever.
P2P transfer works everywhere. Unlimited file sizes require Chrome or Edge.
