Peer-only board and chat
Operations and messages travel on the direct data channel. PdfEditorOnlineFree provides no cloud board, public signaling room, or silent TURN relay.
Live direct collaboration
Sketch together without creating a stored cloud board.
Create a temporary two-person whiteboard that synchronizes drawing operations and chat directly between the participating browsers rather than storing a cloud board. Either participant can export the complete 1920×1080 canvas as a PNG. Both people must keep the page open, exchange connection codes manually, and may be unable to connect through restrictive networks, VPNs, firewalls, or browser policies.
Temporary peer session
Both participants must stay online with this page open. Strict networks may block a direct connection.
Board operations and chat travel only over the peer channel. PdfEditorOnlineFree runs no public signaling room, cloud board, or silent TURN relay.

Deterministic reconnect
Stable operation IDs, ordering, acknowledgements, and missing-operation exchange bring both browsers back to the same board.
Full-board PNG
Export the complete canvas at exactly 1920×1080 pixels without grid, selection handles, participant state, or application chrome.
Vector editing, not flattened pixels
Select, move, resize, restyle, delete, undo, or erase whole vector objects after drawing.
Participant state and chat
See who is connected, whether edits are synchronized, and exchange temporary peer-channel messages.
Honest live-connectivity limits
Both participants must remain online with the page open. Strict networks, VPNs, or firewalls may prevent a direct path.
