About ZapDrop
ZapDrop is a free peer-to-peer file transfer web app: the sender picks a file, shares a private link, and it streams directly to the receiver's browser over WebRTC — no upload, no server storage, no size cap, no account.
ZapDrop lets you send files directly from one browser to another — no upload, no server storage, no size cap. You pick a file, share a private link, and the other person's browser receives it as it streams over an encrypted peer-to-peer connection.
How it works
The transfer uses WebRTC, a browser standard that opens a direct, end-to-end encrypted channel between two browsers. ZapDrop's Cloudflare Worker only coordinates the connection: it hands the two peers the handshake details and nothing else. The file bytes travel straight from the sender to the receiver and are never written to our servers.
Why peer to peer
- No size cap — your file isn't limited by a server quota, only by what the browsers can handle.
- Privacy — the file is never uploaded or stored anywhere.
- Speed — data goes directly between the two people instead of round-tripping through a data center.
Who it's for
Anyone who needs to hand a large file to a colleague, friend, or client without setting up an account or juggling cloud-storage links — and who wants to know the file was never left sitting on a server.
ZapDrop is a neutral peer-to-peer file transfer service. We do not host, moderate, or monitor transferred files and are not responsible for how they are used. Users are solely responsible for ensuring the content they share is lawful, and bear sole legal responsibility for any unlawful use.
