Get FreeFileSending

Opening it the first time

The app isn't signed with a paid certificate yet, so your computer may warn you once.

Windows

1. Open the downloaded FreeFileSending-Setup file.
2. If you see "Windows protected your PC", click More info, then Run anyway.
3. When Windows asks whether FreeFileSending may use your network, click Allow. This lets nearby computers find you.

Mac

1. Open the downloaded .dmg and drag FreeFileSending into Applications.
2. Open FreeFileSending from Applications. If macOS says it can't check the app, click Done.
3. Open System Settings → Privacy & Security, scroll down, and click Open Anyway next to the FreeFileSending message. Confirm with your password.
4. When asked to find devices on your local network, click Allow.

On macOS 13 and 14 you can also right-click FreeFileSending in Applications and choose Open.

Linux

1. Ubuntu or Debian: open the .deb file to install it, or run sudo apt install ./freefilesending_*.deb in the folder you downloaded it to.
2. Other systems: use the AppImage. Make it runnable (right-click → Properties → allow running as a program, or chmod +x FreeFileSending-*.AppImage), then open it.
3. If the AppImage doesn't start, your system may need FUSE 2 (on Ubuntu: sudo apt install libfuse2t64, or libfuse2 on older versions), or use the .deb.
