WhoospHow to share files between devices without installing anything
You are on your phone, the file needs to get to your laptop, and you would rather not email it to yourself, plug in a cable, or install yet another app. Here is a way to do it with nothing but a browser on both ends.
Open WhoospWhat Whoosp is
Whoosp is a free web app that creates a temporary shared room. You open the site, create a room, and get a four-character code and a QR code. Anyone who has that code can join the same room from any device and exchange files and messages. When the last person leaves, the room and everything inside it is destroyed.
There is no account, no sign-up and nothing to install. It runs in the browser on iPhone, iPad, Android, Mac, Windows and Linux, and it can be added to the home screen so it behaves like a normal app.
How to use it, step by step
- Open whoosp.com on the first device and tap Create a room.
- Pick a nickname. You will get a four-character room code and a QR code.
- On the second device, either scan the QR code or type the four characters and tap Join.
- Send messages, photos, videos, audio or documents. Images are compressed automatically so they arrive quickly.
- When you are done, leave the room. The last person out destroys it, and everything goes with it.

Everyday questions, quick answers
Short answers to what people most often ask a search engine or an AI assistant about moving files between phones, computers and other people.
How do I send a photo from my phone to my laptop?
Open whoosp.com on the laptop, click Create a room and scan the QR code with your phone, then send the photo. It works between any phone and any laptop, with no cable and no app. Between Apple devices AirDrop is also quick, and for hundreds of photos a USB cable is better. Every option is compared in how to transfer files from your phone to a PC without a cable.
How do I get a PDF from my phone onto my computer?
Send it through a Whoosp room: on the computer it opens right in the chat, ready to read, download or print. Emailing it to yourself also works, but it takes longer and leaves a copy in your inbox.
How can I send a link or some text from my phone to my computer?
Paste it into a room on the phone and it appears on the computer, ready to click or copy. Handy for long links, addresses and codes you'd rather not type again.
How do I send a screenshot from my phone to my PC?
Take the screenshot, then send it from your photo gallery into a room open on the PC. It arrives as an image you can download.
Can I send a voice memo or an audio file to my computer?
Yes. Audio files up to 15 MB go through a room like any other file, and you can play them from the chat.
How do I move files between a Mac and a Windows PC?
AirDrop doesn't reach Windows. Open a room on both computers and drag the file into the chat. For big folders, use a USB stick or a cloud drive.
How do I transfer files between two computers on different networks?
A browser room works across any networks, because both computers only need internet access. For large folders, a cloud drive is the better fit.
How do I send a file from an iPhone to an Android phone?
Open whoosp.com on both phones, create a room on one and scan its QR code with the other. Pixel 10 phones and some newer Android models can also receive from AirDrop through Quick Share. More in is there an AirDrop for Android and Windows?
How do I send a file to someone without their email or phone number?
Create a room and send them the four-character code, or show them the QR code. They join from any browser, without an account, and get the file. Neither of you sees the other's number or email address.
How do I share a document with everyone in a meeting?
Put the room's QR code on screen: up to 10 people can join at once and download it, and they can send files back. See how to share files with a QR code.
How do I print a document from my phone at a print shop or library?
Ask them to open whoosp.com on their computer and create a room, then scan its QR code with your phone and send the document. If you can't see their screen, create the room on your phone and tell them the four-character code. Details in how to send a file to a computer that isn't yours.
How do I get a file onto a work or school computer where I can't install anything?
Use something that runs in the browser: open whoosp.com on the computer, scan its QR code with your phone and send the file. Follow your organisation's rules for sensitive documents.
Is it safe to log into WhatsApp Web on someone else's computer?
It works, but your chats stay open on that computer until you log out, which you can also do from your phone under Linked devices. For a single file, a room you simply leave is the safer choice.
How can I send files to myself without WhatsApp or email?
Open whoosp.com on both of your devices, create a room on one and join it from the other. Nothing piles up in your chats or your inbox, and the room is deleted when you leave.
What can I use instead of a USB stick?
For a few files, a browser room: the file goes from one device to the other over the internet, with no stick to find or lose. For big folders or backups, a cloud drive or an external drive is still the better tool.
Is there a free way to share files without signing up?
Yes. Whoosp needs no account, no email address and no app, and it's free with no ads. Each file can be up to 15 MB.
How can I share files so they are deleted afterwards?
In a Whoosp room, everything is deleted when the last person leaves, or automatically about 20 minutes after everyone has closed it. Nothing is kept as an archive.
Can I share a large video this way?
Not through Whoosp if it's over 15 MB. For big videos use a cable, AirDrop or Quick Share between nearby devices, or a transfer service such as WeTransfer.
Does it work on a Chromebook, on Linux or on a tablet?
Yes. Anything with a modern browser works: Chromebook, Linux, Windows, Mac, iPhone, iPad and Android tablets.
Are my files private?
Only people with the room code can get in, and transfers are encrypted in transit. Files pass through Google Firebase servers and are not end-to-end encrypted, so don't use it for highly sensitive documents.
How it differs from AirDrop, WeTransfer and peer-to-peer tools
Many browser tools, such as PairDrop, send files directly from one device to the other over WebRTC. On the same Wi-Fi the devices find each other on their own; across different networks you first pair them or join a public room, and both have to stay online until the transfer ends. Whoosp works differently: files wait in a shared room, so the other person can pick them up a minute later, from anywhere. That comes with a real trade-off, explained below the table.
AirDrop and WeTransfer are the other two reflexes, and both have a catch. AirDrop is frictionless, as long as everyone involved owns Apple hardware and is standing nearby. WeTransfer crosses any distance and any platform, but it wants an email address, caps the free plan, and is built around posting a parcel rather than holding a conversation.
| AirDrop | WeTransfer | Peer-to-peer tools (PairDrop, LocalSend) | Whoosp | |
|---|---|---|---|---|
| Works outside Apple devices | No, Apple only | Yes | Yes | Yes |
| Devices must be nearby or on one network | Yes, nearby | No | Same network, or paired first (PairDrop) | No |
| Both devices online at the same time | Yes | No | Yes | No, files wait in the room |
| Email or account | No | Email address | No | No |
| Messages alongside the files | No | A short note | Short texts, no history | Yes |
| People at once | One to one | A link to many | Device to device | Up to 10 in a room |
| Free plan limits | None | 10 transfers or 3 GB a month | None | 15 MB per file |
| When it disappears | Never, it is a copy | After 3 days | Never, it is a copy | When the room closes |
Being straight with you about the trade-off. Whoosp is not peer-to-peer and it is not end-to-end encrypted. Files pass through Google Firebase servers and are encrypted in transit over HTTPS, which is what makes it work across different networks in the first place.
If both your devices are on the same Wi-Fi and you are sending a 2 GB video, a peer-to-peer tool is the better choice. If they are on different networks, or you want several people in one place, or you want to send a link and a photo and a sentence of explanation together, that is where this fits.
Common questions about Whoosp
Do I need to install anything?
No. It runs in the browser. You can optionally add it to your home screen, which just creates a shortcut that opens full screen. There is still no app to download.
Does it work between an iPhone and a Windows PC?
Yes. It is a web page, so it does not care which operating systems are involved. iPhone to Windows, Android to Mac, Linux to iPad: all the same.
Do both devices need to be on the same Wi-Fi?
No. A phone on mobile data can share with a computer somewhere else, with nothing to set up. LocalSend only works on the same network; PairDrop can cross networks, but only after pairing the devices or joining a public room, and both devices must stay online during the transfer.
Is there an AirDrop for Android and Windows?
Not from Apple: AirDrop is only built into Apple devices. Since late 2025 Pixel 10 phones, and during 2026 more Android phones, can exchange files with nearby iPhones through Quick Share. For everything else, such as an iPhone and a Windows PC, or two devices in different places, Whoosp works in the browser. More in Is there an AirDrop for Android and Windows?
What happened to Snapdrop?
Snapdrop, the original AirDrop-style web app, and ShareDrop have been owned by LimeWire since 2025. PairDrop, an open-source fork of Snapdrop, works best on the same Wi-Fi. If you want something that also works across different networks without pairing, with messages alongside the files, Whoosp is an alternative.
How is this different from WeTransfer?
WeTransfer is built for posting a large parcel to someone by email; its free plan allows 10 transfers or 3 GB a month and the links expire after 3 days. Whoosp is built for a short shared session instead: smaller files, no email address, messages and files together, and everything gone the moment you close the room.
How long do the files stay available?
Until the last person leaves the room, at which point everything is deleted. Abandoned rooms are swept automatically, so nothing lingers. It is deliberately not storage: do not use it to keep anything.
How big can a file be?
15 MB per file. Photos are compressed before sending, so ordinary phone pictures go through comfortably.
Is it really free?
Yes, with no account and no advertising.
Can someone else get into my room?
Only with the four-character code, so share it the way you would share a door code, and leave the room when you are finished: leaving is what destroys it.
What can I send?
Text messages, links, photos, videos, audio, PDFs, Office documents and archives.
