Everything you need to know about AirShare
AirShare is a cross-platform file sharing app that lets you transfer files instantly over your local network and across the internet when needed. Local transfers use modern QUIC with TLS 1.3 encryption, while Global Share rides on the Iroh peer-to-peer network for secure long-distance delivery.
Yes! AirShare is free for personal use with limits (200MB file size, 10 transfers/day). Pro version removes all limits and adds unlimited transfer history. One-time purchase, no subscriptions.
No! AirShare works completely offline. No accounts, no cloud, no telemetry. Just install and start sharing.
Yes! All transfers use TLS 1.3 encryption with SHA-256 hash verification. Local transfers stay on your network. Global Share sessions are routed via Iroh, but payloads remain end-to-end encrypted — only the receiving device can decrypt the files.
macOS: Download the .dmg file, open it, and drag AirShare to Applications folder.
Windows: Download the .msi installer and run it. Allow through firewall when prompted.
Linux: Download .AppImage, make it executable (chmod +x), and run.
Common causes:
Quick fix: Restart AirShare on both devices and toggle Discoverability to Nobody → Everyone.
Simply drag and drop files onto any device that appears in your Radar. Or click the device and select files. Transfers start immediately with real-time progress tracking.
Select a global peer from Radar or paste a share ticket. AirShare opens the file picker, generates an Iroh ticket, and copies it to your clipboard automatically. Share the ticket through any channel (chat, email). The recipient pastes it into AirShare to connect.
Global peers you've connected with are remembered, and you can remove them anytime from Radar.
Yes! Select multiple files or drag entire folders. AirShare will queue them and transfer efficiently.
AirShare uses:
Port selection is deterministic based on device UUID, ensuring stable peer identity.
QUIC is a modern transport protocol developed by Google, now standardized by IETF. It's faster than TCP, has built-in encryption (TLS 1.3), and handles packet loss better. Perfect for local file transfers!
The core app is proprietary, but we use many open-source libraries (see Licenses). We're committed to transparency and security.
It depends. AirShare works on most home and small office networks. Corporate networks with strict firewall rules or VLAN isolation may block mDNS multicast. Contact your IT admin if discovery doesn't work.

Pro:
Currently, you can select multiple files from a folder. Full folder transfer support is coming in a future update.
Not yet. If a transfer is interrupted, you'll need to restart it. Resume support is planned for a future release.
Yes. Global Share uses the Iroh networking stack to connect peers worldwide, even through NATs and firewalls. Transfers stay end-to-end encrypted.
If you prefer to keep things local, simply ignore global peers and your traffic stays on the local network.

By default, files are saved to your Downloads folder. You can change this in Settings → General → Download Folder.
Extremely unlikely. All transfers use TLS 1.3 encryption (same as HTTPS). Even on the same local network, transfers are encrypted end-to-end. For global transfers, Iroh routes packets through relays if necessary without seeing file contents.
AirShare has zero analytics or tracking. We only store the minimum license data required (handled by Dodo Payments) and the peer metadata needed for Global Share. Ticket IDs and peer keys synced via Iroh stay encrypted and are kept locally unless you delete them.
All data is stored locally on your device:
~/Library/Application Support/io.github.jaksatomovic.airshare%APPDATA%\io.github.jaksatomovic.airshare~/.local/share/io.github.jaksatomovic.airshareAfter purchase, you'll receive a license key via email. Open AirShare → Settings → License → Enter your key. Activation is instant and works offline after first verification.
Licenses are issued per device. Activating Pro on another Mac, PC, or Linux machine requires an additional license.
If you need to move your license to a different device, contact info@tryairshare.com and we'll help you transfer it.
All sales are final. We do not offer refunds for one-time or lifetime licenses, except where required by law. Please try the free version first to ensure AirShare meets your needs before purchasing Pro.
