Send Files With a QR Code

Step by step

1. Upload on the sending device

   Open send.enzonic.com on the device that has the file, add it, pick an expiry, and upload.

2. Show the QR code

   When the upload completes, a QR code appears on screen along with the link and 6-digit code.

3. Scan with the other device

   Open the camera app on the receiving phone, or the Enzonic Send app, and point it at the code.

4. Open and download

   Tap the link that pops up, enter the password if you set one, and download the file.

You have a file on your laptop and you want it on your phone, or the other way round. AirDrop only works between Apple devices. Emailing it to yourself means logging in and hitting attachment limits. Cables mean finding the right cable. A QR code is often the shortest path: upload on one screen, scan from the other, done.

Two common directions

Computer to phone

This is where QR codes shine, because the computer has the screen and the phone has the camera.

1. On the computer, open send.enzonic.com and drag the file in from File Explorer, Finder, or your Linux file manager.
2. Wait for the upload to finish. The QR code appears.
3. On the phone, open the camera and point it at the screen.
4. Tap the link notification. The download page opens in the phone's browser.
5. Download. On iPhone, Safari saves to the Downloads folder in the Files app. On Android, Chrome saves to Downloads.

Phone to computer

The phone shows the code, so you need something that can read it on the computer side. Most laptops do not scan QR codes conveniently, so in this direction the 6-digit code is usually easier: upload on the phone, then type the six digits on the computer at send.enzonic.com/receive. See sharing files with a 6-digit code.

If the receiver is another phone, the QR code works perfectly in this direction too. Hold one phone up, scan with the other.

Scanning on each kind of phone

iPhone and iPad. The Camera app reads QR codes by default. Point it at the code and a yellow link button appears near the code; tap it. You can also add the Code Scanner to Control Center for faster access.

Android. On most phones the camera app or Google Lens reads QR codes. Some manufacturers put the scanner in the quick settings panel instead. If your camera does not react, try Google Lens.

Enzonic Send app. The Android and iOS apps include a QR scanner that opens the transfer directly inside the app.

Why the QR code still works after you close the tab

A lot of "scan to transfer" tools are peer-to-peer. They create a live connection between two devices, which means both screens must stay open until the transfer finishes. Enzonic Send uploads the file first and stores it on Cloudflare's network. The QR code is just the share link encoded as an image.

That has a few practical consequences:

• You can close the browser tab on the sending device as soon as the upload completes.
• The receiving phone does not need to be on the same Wi-Fi. Mobile data works.
• A screenshot or photo of the QR code works later, until the transfer expires.
• You can show the same QR code to several people in a room, subject to any download limit you set.

Things that stop a QR code from scanning

Quick fixes, roughly in order of how often they are the problem:

• Screen too dim or glare on it. Turn up brightness, tilt the laptop screen.
• Too far or too close. The code should fill about a third to half of the camera frame.
• Dirty lens. Phone cameras collect fingerprints. Wipe it.
• Dark mode or night filters. Blue-light filters rarely matter, but heavy color filters can. Turn them off briefly.
• Old phone camera without QR support. Use Google Lens, the Enzonic Send app, or just type the 6-digit code.

When not to use a QR code

QR codes are for people in the same place. If the receiver is somewhere else, sending them a photo of a QR code works but is clumsy; copy the link instead. And if the file is private, remember that anyone who photographs your screen can open the link. For sensitive files, set a password, a download limit of 1, and the 1-hour expiry, and delete the transfer once it has been picked up. Enzonic Send encrypts files in transit and at rest, but it is not end-to-end encrypted. More in password-protected file sharing.

Limits to keep in mind

• 500 MB per transfer without an account, 2 GB with a free account (email or Google).
• Expiry of 1 hour, 1 day or 3 days anonymously, up to 7 days when signed in.
• Originals are kept. Photos and videos are not recompressed, which matters if you are moving video from an iPhone and want the full quality version on your computer.
• Multiple files are zipped in the browser into one archive, so one QR code covers the whole batch.
