Features

Send it, and it's there.

Nothing goes through the cloud, so it's fast — and big files are no problem.

Originals, untouched
Photos go as HEIC, videos as MOV — the files exactly as you shot them. Edited photos are sent as edited. No loss in quality.
Fast
Everything you pick streams over a single connection, so hundreds of photos go without waiting. You see the speed (MB/s) while sending.
Picks up where it left off
If Wi-Fi drops for a moment, it reconnects on its own and continues. Files the other side already has aren't sent again.
Keeps going with the screen off
Turn off the screen while sending — it finishes anyway. Progress shows in the notification.
Encrypted, with a confirmation code
Everything is encrypted. The first time two devices meet, you compare a code shown on both screens and allow it. After that, no more prompts.
No cloud
Files travel directly between your devices and never pass through a server. No account needed.
Organized on your Mac
On a Mac, Viaduct waits in the menu bar. It can sort files into a folder per sending device, or save each device's files wherever you like.
Whole folders (Pro)
Pick a folder and it arrives with the same structure inside.
Meta Quest too
Filter your Quest screenshots and recordings and send them straight to your Mac or phone. Videos you receive can be watched right in Quest.
How it works

Three steps

Open the receiving side

On a Mac or Windows PC, keep Viaduct running. Phones and Quest can receive while the app is open.

Pick what to send

Choose from your recent photos and screenshots, or pick files or a folder, then tap the device to send to. On Android you can also send from the share menu.

Confirm once

The first time, check that the code on both screens matches and allow it. Then just wait for it to arrive.

Requirements

Requirements & notes

Requirements

  • iPhone & iPad — iOS 16 or later
  • Android — Android 10 or later
  • Mac — macOS 13 or later
  • Windows — in the works
  • Meta Quest — coming to the Meta Horizon Store
  • To send over home Wi-Fi, both devices must be on the same network (same Wi-Fi or LAN)

For the best experience

  • Guest Wi-Fi networks, or networks that block devices from talking to each other (AP isolation), may keep devices from finding each other
  • On iPhone and iPad, allow "Local Network" access the first time you open the app
  • Large files go faster on 5 GHz or faster Wi-Fi
