How to send a file to a computer that isn't yours

You're at the office, a library, a print shop, a hotel or a school, and the file you need is on your phone. You could log into WhatsApp Web or your email on that computer, but then your account is open on a machine you don't control. The cleaner way: open a temporary room in the browser, scan it with your phone, send the file, then leave. There's nothing to log out of.

Why not WhatsApp Web or email?

Your account stays on that computer. WhatsApp Web keeps the computer linked to your account until you log out, and a browser may remember your email login.
Other people use the same machine. Whoever sits there after you could read your chats or your inbox if you forget to sign out.
It's slow. Scanning a login code, waiting for your chats to load, finding the file and downloading it takes longer than the file deserves.

If you already logged in somewhere, you can still end the session from your phone: in WhatsApp, open Linked devices and log out of that computer.

How to do it with Whoosp

On the computer, open whoosp.com and click Create a room.
Scan the QR code on the screen with your phone's camera.
Send the file from the phone. It appears on the computer a moment later.
Open it, print it or download it on the computer.
When you're done, leave the room on both devices: when the last person leaves, the room and the file are deleted.

If you can't see the computer's screen, for example at a shop counter, do it the other way round: create the room on your phone and read the four-character code to the person at the computer, who types it at whoosp.com.

At a print shop

Many print shops ask customers to email their files or send them to the shop's WhatsApp number. With a room, the file goes straight to the shop's computer, and neither side has to share an email address or a phone number. PDFs, photos and Office documents up to 15 MB each go through, and the room disappears when you're done.

At the office, a library or university

Shared and managed computers often don't let you install anything. Whoosp only needs a browser, so it works there too, and nothing is left installed afterwards. Some organisations block websites they don't know: if the page doesn't open, ask whoever runs the computers.

Sending files to yourself

Lots of people move files by sending them to themselves on WhatsApp or Telegram, or by emailing themselves. That works on your own devices, but it fills your chats with copies and needs you to be logged in at both ends. A room does the same job without an account: open whoosp.com on both devices and send.

Before you walk away

Leave the room, so the files are deleted from Whoosp.
Delete the file from the computer's Downloads folder if it was private.
Close the browser tab or window.

Common questions

Is it safe to use Whoosp on a public computer?

You never type a password, so there's no account left open. Files are encrypted in transit and deleted when the room closes. The one thing to remember is the downloaded copy: delete it from the computer if it's private.

Do I need to install anything on the computer?

No. Any modern browser is enough: Chrome, Edge, Safari or Firefox.

What if the computer has no camera?

It doesn't need one: your phone scans the code shown on the computer's screen. If that isn't possible, type the four-character code instead.

What can I send, and how big can it be?

Photos, videos, PDFs, Office documents, archives and audio, up to 15 MB per file.
