qrr.app is a website that lets you share files from browser to browser – instantly, without installing any apps or creating an account.
Just open the site, scan a QR code, and you're done – you can send a photo, document, or video.
1. When a friend wants your photo – but you don't have Messenger
You take a photo with your phone, but your friend doesn't have WhatsApp, and you don't want to send an MMS?
Open qrr.app, create a session, show them the QR code – and the photo lands on their device in seconds.
No accounts, logins, or registration.
2. Transferring files from laptop to phone… without a cable
You know the feeling? You have a PDF presentation or document on your laptop and want to quickly get it on your phone.
Instead of searching for a cable or uploading to Drive – just open qrr.app on both devices and scan the QR code.
What if the situation is reversed and you want to send from your phone to any other device? You do it exactly the same way!
"TIP If one of the devices has a camera, create a session from the device without a camera, then you can take advantage of scanning the QR code with the other device's camera and connect even faster!"
3. When someone says: "Send it quickly, I'm leaving"
You don't have time to explain how Dropbox works or where the email attachment is.
With qrr.app everything takes 10 seconds – you send a link, and the other person receives the file instantly.
4. In class, at work, in the library – sharing notes and screenshots
Whether you're a student, teacher, speaker, or training participant.
When you want to share notes, slides, or screenshots – qrr.app is the simplest way: open the site, select a file, and give the other person a QR code. Running a presentation and want to quickly send something to the audience? Instead of asking for email addresses, just show them the QR code and send it instantly.
5. Transferring files between different operating systems
You have an iPhone, and the other person has Android? You're on Windows, and they're on a MacBook?
For qrr.app that's no problem – all you need is a browser and internet access.
Works on iOS, Android, Windows, macOS, and Linux – no hassle and no installation required.
