Waking up droprtc…
Droprtc is a free peer-to-peer file transfer tool that runs entirely in your browser. Instead of uploading your files to a cloud server and waiting for someone to download them, Droprtc opens an encrypted connection straight between your device and theirs — so there is nothing to install, no account to create, no upload quota, and no copy of your data left sitting on a server.
Files stream device-to-device, so there is no upload cap. Gigabyte videos, raw photo folders, disk images — if your devices can hold it, you can send it.
Every session uses fresh DTLS keys with AES-GCM encryption, and peers must cryptographically prove they hold your link before anything flows.
No cloud bucket, no expiring download page, no logs. When the tab closes, the session and its keys are gone for good.
The QR code makes Droprtc a fast way to move photos and videos between a phone and a computer: open the site on the computer, scan the code with the phone, and send in either direction. iPhone, Android, Windows, Mac and Linux all work together, because everything runs in the browser each device already has. On the same Wi-Fi, the connection stays inside your router and transfers run at local-network speed — often hundreds of megabits per second, far faster than routing a large file through the internet and back.
Traditional file-sharing services move your data twice — an upload to their storage, then a download to the recipient — and pay for that with size caps, wait times, expiring links and accounts. A direct peer-to-peer transfer moves your data once, from you to them, while both of you watch the same live progress. The sender even sees exactly how much the receiver has confirmed, so "done" genuinely means the file arrived intact.
Yes — and you can read exactly how in the app's "How is this secure and fast?" panel, which walks through every step. In short: browsers negotiate end-to-end DTLS encryption with keys that never leave your devices; the session secret in your link is carried in the URL fragment, which browsers never transmit to any server; and every peer must answer a cryptographic challenge — bound to the connection's own certificate fingerprints — proving they hold that secret before a single file name is revealed. Verified peers display a safety code that matches on both screens. The one rule to remember: your link is the key to the session, so share it only with people you want in.
No hard limit. Files stream directly between the two browsers, so there is no upload quota. Very large files are held in browser memory while they transfer, so the practical ceiling is the receiving device's free memory.
No. Files travel directly from one browser to the other over an encrypted WebRTC connection. A small signalling service only introduces the two browsers and never sees file names or contents.
Yes. There is no account, no premium tier and no size-based paywall. The project is supported by donations.
Yes. A transfer is a live pipe between the two browsers, so both tabs must stay open until it completes. The sender's progress bar shows exactly what the receiver has confirmed.
Yes — any mix of iPhone, Android, Windows, Mac or Linux, as long as each device has a modern browser. Scan the session QR code with a phone camera to connect instantly, no app install needed.
Every connection is end-to-end encrypted with DTLS and AES-GCM using keys generated fresh for the session. On top of that, peers must cryptographically prove they hold your link's secret before any data flows, which locks out both intruders and man-in-the-middle relays.
The transfer is marked failed on both sides rather than left hanging. Reconnect and send again, or use the session's shared-file list to pull the file from any peer that has it.
Yes. Any number of peers can join one session link. Files you share are offered to everyone, and every peer can pull any shared file whenever they want it.
Droprtc is free, independent software with no ads and no tracking, kept running by its users — if it saved your day, consider supporting the developer.
