Send files directly device-to-device over WebRTC — files never touch NotesQR's servers.

No signup. No size quota. Browser, desktop, extensions, CLI, and MCP. Both peers stay online during the transfer; that is the tradeoff for not storing your files.

NotesQR is donation-funded. If a transfer saved you time, support the project.

Drop a file → get a room link or QR → the other device downloads. Signaling helps peers find each other; file bytes travel peer-to-peer.

First-class for terminals and AI agents — same WebRTC rooms as the web app. Needs Node.js 18+.

# Terminal A — sender (exits after successful delivery with --once)
npx -y github:NotesQR/notesqr-share send ./file.pdf --once

# Terminal B — or open the printed URL in a browser
npx -y github:NotesQR/notesqr-share recv https://notesqr.com/xxx-xxxx-xxx -o ./out

Folders work the same way (send ./project/ --once). MCP config and more commands: NotesQR/notesqr-share.

Factual split — they upload to provider storage so the receiver can fetch later. NotesQR does a live P2P handoff.

• WeTransfer — upload-and-store link. Files sit on their servers for the link lifetime; free tiers cap size and expiry. NotesQR never hosts a download archive.
• Dropbox — cloud sync/storage (and Dropbox Transfer). Needs an account and quota. NotesQR needs no account on either side.
• Google Drive — share a copy that lives in Google’s cloud. Account required for normal use. NotesQR is a live room, not a drive.

Full comparison · P2P vs upload-and-store

When they win: the sender cannot stay online. When NotesQR wins: you do not want a hosted copy, an account, or a size quota.

TURN is a fallback only, when a direct peer path is blocked (symmetric NAT, etc.).

1. Sender creates a room and offers files (or a folder).
2. NotesQR handles signaling so peers can find each other.
3. Receiver opens https://notesqr.com/<room-id> or runs notesqr recv.
4. Bytes move device-to-device while both sides stay online.
5. When it finishes, NotesQR does not keep a hosted copy for later anonymous download.

If the sender closes the tab/app/CLI before the download completes, the transfer stops. That is by design.

The public CLI/MCP client is MIT (notesqr-share). The hosted signaling at notesqr.com is what the live product uses.

1. Go to https://notesqr.com
2. Drop files → Start Sharing
3. Copy the room URL or show the QR
4. Keep the sender page open until the other device finishes downloading

Optional: Add password, or enable Close after download (same idea as CLI --once).

• No signup / no account to send or receive
• Unlimited size within what your devices and network can sustain
• WebRTC P2P (TURN only when needed)
• Room URL + QR for phone ↔ laptop
• Optional room password
• Folders with share-relative paths only (never absolute disk paths)
• Close after download / CLI --once
• Locales: English, Español, Français, Deutsch, Italiano, Português
• CLI + MCP for scripts and AI agents

• File bytes travel over WebRTC between peers. NotesQR provides signaling and TURN when a direct path fails.
• Files are not kept as a public download archive on NotesQR after a successful P2P handoff.
• Treat an unpassworded room link like a secret. Optional room password gates joining.

Yes. notesqr.com is free for P2P sharing. The project is donation-funded.

No.

File contents are not stored on NotesQR for later retrieval. Peers exchange data over WebRTC. Both sides must stay online until the download finishes.

Yes. npx -y github:NotesQR/notesqr-share (send / recv) and the MCP server (notesqr-mcp). Prefer --once for send so the host exits after delivery.

Yes. Open the room URL or scan the QR. The sender must remain online.

The live P2P path ends.

NotesQR (https://notesqr.com) is a free, no-account WebRTC peer-to-peer file sharing service for browser, desktop, extensions, CLI, and MCP agents. Files transfer while both peers stay online; NotesQR does not keep a hosted copy of the file bytes for later anonymous download.
