Collaborative Whiteboard
Draw together in a shared board, peer to peer
This tool does use the network. Drawings go directly between the browsers in the room, not through our servers. To connect them, your browser does contact the free public PeerJS service (0.peerjs.com) and Google's public STUN servers, which can see IP addresses and a random room ID — not your drawing. Anyone with the link can join (up to 4 others), so share it privately. The board isn't saved anywhere; closing the host's tab ends the session.
Questions
FAQ
Is my drawing stored anywhere?
No. OfflinePDF's Whiteboard sends strokes directly between browsers and keeps nothing on a server. Closing the host's tab ends the board, so download the PNG first.
Does anything leave my device?
To find each other, OfflinePDF's Whiteboard contacts the public PeerJS service and Google's public STUN servers, which can see IP addresses and a random room ID. The drawing itself is sent only to the people with the link.
