PairDrop
GPL-3.0Open-source cross-platform alternative to Apple AirDrop. Share files directly peer-to-peer in any web browser without accounts, apps, or cloud uploads.

Overview
A household with an Android phone, a Windows laptop, and an iPad needs to share vacation photos without uploading private albums to cloud storage. Email attachments reject large video clips, and proprietary protocols refuse to connect across competing operating systems. PairDrop opens in any browser to transfer files directly between nearby screens over encrypted WebRTC connections.
Why PairDrop instead of Apple AirDrop
Apple AirDrop relies on proprietary wireless protocols that restrict discovery and transfers to Apple hardware. An Android phone or Windows PC cannot communicate with an Apple device through AirDrop. PairDrop removes that barrier using open web standards. By coordinating discovery over WebSockets and streaming bytes through WebRTC inside the browser, PairDrop establishes encrypted peer-to-peer transfers across Android, Windows, Linux, macOS, and iOS without requiring native applications or administrative rights.
Network integration differs as well. AirDrop demands physical proximity with active Bluetooth and Wi-Fi, failing across separate subnets, cellular connections, or VPNs. PairDrop connects devices across distinct networks via six-digit codes or temporary web rooms, utilizing TURN relays when NAT traversal requires a fallback. Unlike cloud services like WeTransfer that require uploading payloads to remote storage and waiting for download links, PairDrop delivers files directly in real time, keeping private media off third-party servers.
What it does well
- Zero installation: users open the website in Chrome, Safari, Firefox, or Edge to transfer files without accounts, passwords, or app downloads.
- Automatic local discovery: devices on the same Wi-Fi appear as distinct icons with clear names, making recipient selection simple.
- Mobile share sheet integration: supports native share menus on Android and iOS, letting users forward photos directly from camera rolls.
- Multi-file ZIP packaging: bundles multiple incoming files into a single compressed ZIP archive, keeping download folders organized.
- Cross-network pairing: connects devices across separate Wi-Fi networks or VPNs using a six-digit code or QR code.
- Media previews: displays visual and audio previews for incoming images, sound files, and video clips so recipients can inspect content before accepting.
