How to transfer files between two computers
By the WispFile team · Updated 24 September 2026
To transfer files between two computers without a cable, open a direct browser transfer on one and a link on the other: the files stream straight across, on the same network or across the internet, with nothing to install. A USB drive, network share or cloud folder also works; which is best depends on whether the computers are side by side, what systems they run, and how big the files are.
Key facts
- Same room, huge files: Ethernet or the same fast network.
- Different systems (Windows ↔ Mac): a browser link avoids format and sharing setup.
- Different places: a direct transfer or cloud storage.
- Nothing installed: a browser-to-browser transfer.
Your options compared
| Method | Setup | Across the internet | Size limit | Cross-platform |
|---|---|---|---|---|
| USB drive or external SSD | A drive with space; the right disk format | No (only by post) | The drive’s capacity | Needs exFAT for Windows ↔ Mac |
| Network shared folder (SMB) | Sharing settings, same network | No | Disk space | Yes, with setup |
| Cloud storage | Accounts; upload then download | Yes | Your quota | Yes |
| Built-in (AirDrop, Nearby Share) | None | No, nearby only | Practical limits | Same ecosystem only |
| Direct browser transfer (WispFile) | None: a browser | Yes | None set | Yes |
When a USB drive still wins
For hundreds of gigabytes between two machines on a desk, a fast external SSD is hard to beat, and it needs no network at all. Format it as exFAT if it has to work on both Windows and macOS. The costs: you need the drive, you copy twice (on and off), and a drive can be lost with the files on it.
When a direct transfer wins
When the computers are in different places, run different systems, or you do not want to set up sharing or create accounts. Open WispFile on the sending computer, add the files and share the link; open the link on the other computer and download. The files travel directly, encrypted, and are written to disk as they arrive. On the same network the transfer runs at local speed; across the internet, at the speed of the sender’s upload.
Step by step
- On the sending computer, open wispfile.com in Chrome or Edge.
- Add files, or drop a whole folder to keep its structure.
- Get the link and move it to the other computer: email or message it to yourself, or scan the QR code with a phone that can open it.
- On the receiving computer, open the link, press Download all and choose a folder.
- Keep the sending computer awake until it finishes.

Frequently asked questions
What is the fastest way to transfer files between two computers?
In the same room, a direct connection on the same network or an Ethernet cable is fastest. Across the internet, a direct browser transfer is fastest for the person waiting, because it does not upload first and download second.
Can I transfer files between two computers without a USB drive?
Yes. Over a network with a shared folder, with cloud storage, or with a direct browser transfer that needs nothing installed on either machine.
How do I transfer files from Windows to Mac?
Open WispFile on the Windows PC, add the files, and open the link on the Mac. The files arrive exactly as sent; there is no disk format or network share to set up.
Do the two computers need to be on the same network?
No. A direct browser transfer works across networks and countries. Being on the same network simply makes it faster.
