Typing a long link onto a phone is slow and error-prone. A QR code removes that friction entirely: point the camera, tap the notification, and the download opens instantly.

That makes QR codes ideal in a few everyday situations:

• In person. Sharing files in a meeting or classroom? Let people scan the code off your screen instead of spelling out a URL.
• Across your own devices. Send from your computer and open on your phone in seconds, with no messaging app in between.
• On printed materials. Add the code to a flyer or slide so anyone can grab the files later.

Every transfer comes with its own QR code automatically — nothing extra to set up. It’s a small feature that saves a surprising amount of time, especially when you’re sharing with more than one person.
