Setup
Everything happens on the PC that should receive your documents. It takes about two minutes, and the phone app is free.
You need to be on the PC itself. Snap2PC is a Windows program, so it cannot be installed from a phone. If you are reading this on your phone, type snap2pc.com/setup into a browser on the PC instead.
Get it from the Microsoft Store. Microsoft signs and verifies the package, so it installs like any other Store app — no security warning, nothing for your antivirus to object to — and it keeps itself up to date afterwards. It runs in the tray and adds the firewall rule it needs. When it has installed, open Snap2PC once from the Start menu: installing does not start it. From then on it starts by itself whenever you sign in. Windows 11 is required.
If you would rather install it directly, you can
download the installer (.exe, 62 MB)
and run it — it installs to C:\Program Files\Snap2PC. Windows Defender or
your antivirus software may complain about it because the file is new rather than
because anything is wrong with it; you can carry on past that and install it. The two
sections below are about that path only.
Some antivirus products flag it. It is not infected, and you do not have to take our word for it — the checksum is published below.
Snap2PC-Setup-0.4.9.exe is 62 MB and its SHA-256 is:
05e2571e19d06859a3db7a4ea89b9542a273cb2e530a466d0707197209e155d1
On the PC, certutil -hashfile Snap2PC-Setup-0.4.9.exe SHA256 should
print exactly that. If it does not, do not run it — tell us at
[email protected].
To a scanner the downloaded file is an unknown program with no reputation that writes to Program Files, adds a firewall rule and sets itself to start with Windows. That is a reasonable thing to be suspicious of, and it is a judgement about the file being new rather than about what it does.
The Store version is not affected: Microsoft signs and verifies that package, which is why it installs without any of this. If your antivirus is making the direct installer difficult, installing from the Store instead is the shorter road.
You may see a blue box saying “Windows protected your PC”. Click More info, then Run anyway.
This appears because that file is new and has not built up a reputation with Microsoft SmartScreen — not because anything is wrong with it. It is worth saying plainly rather than hoping you do not notice: it is the step most people stop at, and it is the whole reason the Store is the recommended route above.
When it first runs, Snap2PC asks which folders your phone is allowed to send to. Pick the ones you actually file into — a client folder on the desktop, a folder on a network share, whatever you already use. You can add more later.
This is the part that does the work. Documents arrive already named and already in the right folder, so there is nothing to rename and nothing to drag anywhere.
Install the Snap2PC app on the phone first. It is free and needs no account.
That is the whole setup. The code is good for three minutes and works once — if it expires, just show another.
Scanning the code off the screen is also what makes the connection private. The keys travel over light rather than over the network, so nobody sitting on your Wi-Fi can intercept or substitute them. There is more on this in Security.
Three things account for nearly every case.
The phone never needs one. There is nothing to sign up for and nothing to sign in to: install the app, scan the code shown on your PC, and start sending. Personal use on your own network is free for a limited time.
Businesses register on the web rather than on the phone. Create an account at snap2pc.com/signup, then claim each receiving PC from the Snap2PC window on that PC — it asks for your account once, because a PC being claimed belongs to whoever is claiming it. Commercial use is free for the first month, then $9.99 per receiving PC per month — see pricing.
The installer is an Inno Setup package and takes the usual switches, so it deploys from an RMM without anyone touching the machine:
Snap2PC-Setup.exe /VERYSILENT /NORESTART /SUPPRESSMSGBOXES
The firewall rule is added during the elevated install, so no prompt appears for the user. Note that the rule is bound to the installed program path — running a copy from somewhere else means inbound connections are silently dropped, which looks exactly like a switched-off PC.
Snap2PC runs in the user's session rather than as a Windows service. That is deliberate: a service running as LocalSystem has no user network credentials and cannot write to a UNC path without a domain service account. Running in the session means it inherits the signed-in user's share permissions with nothing to configure.
