QR Code File Transfer
Open IcyZip on one device, scan the QR code with another browser, and move live text or one selected file between phone, computer, laptop, or tablet.
- QR pairing. Scan once to connect the second browser to the same temporary session.
- Browser only. Use phone and computer browsers without account login or an app install.
- One selected file. Send a chosen file while both browsers remain connected.
How it works
Use the QR code as the connection step
IcyZip is built for short-lived device handoffs. The QR code does not publish a file; it helps the second browser join the paired session.
Scan with the other
Use the second device to scan the QR code or open the pairing link.
Transfer in the session
Use live text immediately, or choose the file action to send one selected file.
Device handoffs
QR transfer for common phone and computer moments
Phone to PC
Scan from a phone and send a photo, export, document, link, or code to the computer browser.
PC to phone
Move text or one selected file to a mobile browser without emailing it to yourself.
Browser to browser
Pair two browsers directly for a quick live exchange instead of setting up a shared folder.
Temporary transfer
Use IcyZip when you need a short handoff, not a permanent file-sharing link.
Privacy and limits
What the QR code does and what metadata remains
Current product browser clients encrypt live text and file bytes in the browser. The service relays encrypted data for the paired views and still processes operational metadata needed to run the session.
Pairing link, not public storage
The QR code opens a browser pairing link. It is not a public download page or a cloud folder.
Encrypted browser payloads
Current browser clients encrypt live text and file bytes before sending them through the service.
Metadata remains visible
Timing, IP-derived country where configured, browser class, message sizes, filename, file size, type hint, and transfer control identifiers may be visible to the service.
First-release size limit
The current first-release file size limit is 25 MiB unless the server configuration is changed.
FAQ
QR code file transfer questions
How do I transfer a file with a QR code?
Open IcyZip on one device, scan the QR code with the other device, wait until both browsers are connected, then choose the file action and send one selected file.
Does the other person need an app?
No. IcyZip runs in the browser. The QR code opens the pairing link in the second browser.
Can I use it from phone to computer?
Yes. Start on the computer, scan with the phone, and transfer text or one selected file while both browsers stay connected.
Is the QR code a permanent download link?
No. IcyZip is designed for transient paired browser transfer. It does not provide public file links, shared folders, or offline file pickup.
What should I read before using sensitive files?
Read the privacy policy and the limits above. Payloads are encrypted by current browser clients, but connection and transfer metadata still exists.
