How to Share Files With a QR Code

• Face to face: a client in your studio, a colleague at the next desk, a parent at the school gate.
• A room of people: a classroom, a workshop, a conference talk or an event table.
• Print: a notice board, a product box, a menu or a visiting card that should lead to a file.

1. Upload your files with Get a link selected and press Get link.
2. When the upload finishes, the QR code appears next to the link, labelled Scan to download.
3. The other person scans it with their phone camera. No app is needed on either side.
4. To pass the code itself on, press Download QR (saves a PNG) or, on phones, Share QR.

If you set a custom short link, the QR code opens that address.

1. On your Transfers page, press More on the transfer and choose QR poster.
2. Type a Title and an optional Short message, and choose whether to Show the expiry date.
3. Press Print or save as PDF. Only the poster is printed: a large black-on-white code, "Scan to download", and the link written underneath for people who prefer typing.

If the transfer has a password, the poster says "Ask the sender for the password" instead of printing it. Each personal link has its own Poster button, labelled with that person's name, so each team or room can have its own code.

Dev runs a photography workshop and wants all 30 participants to get the presets and a sample RAW file. He uploads them, makes a QR poster titled "Workshop files", shows the expiry date and puts the PDF on his last slide. Participants scan from their seats; anyone who missed it types the short address printed under the code. Afterwards Stats show how many downloaded.

Their camera app shows the link; tapping it opens the download page in the browser, with the files, sizes and a Download button. Any password, confirmed email or download limit you set applies as usual.

A laptop has no camera app for QR codes, but the Receive page does: press Scan QR code, allow camera access once, and hold the code up to the webcam. The download page opens on that device. For codes on a projector, scan from the middle of the room first to check the size.

• A QR code is just the link. Anyone who photographs a poster can open it, so add a password, a confirmed email, a download limit or a closing time for anything private.
• It stops working when the transfer expires after 1 day. Showing the expiry date on the poster avoids confused scans later.
• Email transfers have no QR code or poster, because each recipient gets a private link.
• Only the sender can open the poster page, from the browser they sent from or when signed in.

• Test-scan the printout, and print it large enough for the distance people will stand at.
• The camera does not react: use the Scan QR code button on the Receive page, or type the link.
• No Share QR button: your browser cannot share images; use Download QR.
• Need a QR code for something else, like a website or Wi-Fi details? Use the free QR code generator.
• The poster says only the sender can make it: open it from the Transfers page in the browser you sent from, or sign in first.
• People scan an old poster: the transfer has expired. Press Keep it longer on the Transfers page before the date, or print a new poster for a new transfer.
