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. Think AirDrop, but for macOS, Windows, and Linux. Uses modern QUIC protocol with TLS 1.3 encryption for fast, secure transfers.
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. Files never leave your local network and are transferred directly peer-to-peer. SHA-256 hash verification ensures file integrity.
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.
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.
No. AirShare is designed specifically for local network transfers. It uses mDNS which only works on the same local network. This is a security feature - your files never leave your 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. Only the receiving device can decrypt the files.
No. AirShare has zero telemetry, zero analytics, zero tracking. Everything stays on your device. We never see your files, transfer history, or usage patterns.
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.
Yes! One license works on all your devices (Mac, Windows, Linux), but can only be activated once. After activation, it works on all your devices. Contact info@tryairshare.com if you need to transfer to a different account.
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.
