QR Code File Transfer: Connect Devices and Fix Scan Problems

The QR code encodes a session link. It does not contain your photo or document. Scanning opens a temporary room; the sender still needs to upload a file, and the receiver still needs to download it.

The link provides access to that room. Anyone who obtains it may access the session, so avoid posting its QR code in public screenshots. HTTPS protects traffic in transit but does not make possession of the link harmless.

Open WebDrop on the sending device and create a session. Scan its code on the receiving device, then open the browser prompt. Confirm you are on webdrop0.com and that both screens refer to the same session.

Choose a file and wait until it is listed. Download it on the receiving device and open the saved copy. Closing a browser tab does not delete the session or revoke a shared link. The session expiry is measured from creation, not from the most recent scan.

Make the whole code and its surrounding border visible. Reduce glare, adjust screen brightness, clean the lens, and move the camera back until it can focus. A cropped screenshot or a code partially covered by another window may not scan.

If scanning is unavailable, enter the displayed session code in WebDrop’s join form or open the session link on the other device. This joins the same room; it does not create a separate transfer.

Once the browser opens the correct URL, QR recognition has succeeded. If the room is missing or expired, create a new session and share its new code. Retrying the same expired image will not restore the old room.

If the room opens, send a short text message. If that arrives, focus on file size, upload completion, and the receiver’s download. A scan problem and a storage or network error need different fixes.
