What it does
Finds your devices by itself
Open it on two devices on the same Wi-Fi and they show up in each other’s list. On networks that hide devices, scan the computer’s QR code with your phone.
Friends don’t need the app
Choose Receive files and your computer shows a short address and a QR code. A friend opens it in their phone’s browser and drops photos and files straight onto your computer.
Photos from your phone in a few taps
Share from Photos, pick ZuperDuper, tap the computer. iPhone photos arrive as JPEG on computers that can’t open HEIC, with their date and location intact.
Files of any size
Send whole folders. If the Wi-Fi drops or a laptop goes to sleep, the transfer carries on where it stopped.
Chat across the room
Message one device, or every device at once in #everyone. Little ticks show when a message has arrived.
Your list, your rules
Give devices names you recognise, pin the ones you use, accept files automatically from some and ask first for others, and block anyone who sends junk.
It stays between your devices
Your files go straight from one device to the other over your local network. There’s no ZuperDuper server in the middle, so there’s nothing to sign up for and nothing stored anywhere else.
Every connection is encrypted, and each device has its own key, so one device can’t pretend to be another.
Updates
On Mac, Windows and Linux, ZuperDuper checks this site for new versions. When there is one, it tells you, and one click installs it and restarts the app. Every update is signed, and the app installs nothing that isn’t. On Android, the app shows you when a new version is ready to download.
