Step by step
Upload the file
Open send.enzonic.com, add your file or folder, choose an expiry, and start the upload.
Note the code
When the upload finishes, a 6-digit code appears next to the link and QR code.
Pass it on
Tell the receiver the six digits by voice, text or any other way. You can close the tab now.
Receiver enters it
The receiver opens send.enzonic.com/receive, or the Enzonic Send app, types the code, and downloads the file.
Links are great when you can paste them. They are terrible when you cannot: over a phone call, on a smart TV browser, on a locked-down work PC with no chat app, or on a public computer where you do not want to log into your email. A 6-digit code solves that. Six numbers are easy to say, easy to remember for a minute, and easy to type on any keyboard.
What the code actually is
When an upload finishes on Enzonic Send, you get three things at once: a share link, a 6-digit code and a QR code. All three lead to the same transfer. The code is simply the version designed for humans to type.
The receiver goes to send.enzonic.com/receive, enters the digits, and gets the download. If you set a password, they are asked for it next. If you set a download limit, each download counts toward it, whichever route the person used to get there.
Where a code beats a link
| Situation | Best option | Why |
|---|---|---|
| You are on a phone call | Code | Six digits take seconds to read out |
| Same room, phone and laptop | QR code | Point the camera, done |
| Chat, email, or a ticket system | Link | Click and download |
| Public or library computer | Code | Nothing to log into, nothing long to type |
| Smart TV or console browser | Code | Typing a URL with a remote is painful |
| Someone reading from paper | Code | Short, no ambiguous characters in a long URL |
The code is numbers only, so there is no confusion between a capital I and a lowercase l, or a zero and the letter O.
Entering a code on different devices
Windows, Mac, Linux, ChromeOS. Open any modern browser, go to send.enzonic.com/receive, and type the six digits. The file lands in your Downloads folder.
iPhone and iPad. Open Safari and go to the receive page. After you tap download, Safari saves the file to the Downloads folder in the Files app, unless you have changed that location in Settings. Photos and videos can then be saved to the Photos app from there.
Android. Open Chrome, go to the receive page, enter the code, and the file goes to Downloads. Open it from the Files app or Chrome's download list.
The Enzonic Send app. On Android and iOS, the Enzonic Send app has a field for the code and can also scan QR codes, if you would rather not use the browser.
Not the same as a pairing key
Some tools use a short key that only works while both devices are online. Send Anywhere's 6-digit key, at the time of writing, is valid for about 10 minutes and needs the sender's device to stay connected. Peer-to-peer tools like PairDrop work in a similar live way.
Enzonic Send is different because the file is uploaded first and stored on Cloudflare's network. The code points to a stored transfer, not to a live connection. In practice:
- You can upload at your desk, close the laptop, and the code keeps working.
- The receiver can enter it an hour later, or the next day, depending on the expiry you chose.
- A flaky connection on the sender's side after the upload finishes does not matter.
If that live, both-online model is what you are moving away from, our Send Anywhere alternative page compares the two in more detail.
Keeping a short code safe
A 6-digit code is convenient precisely because it is short, and short also means easier to guess than a long random link. For holiday photos that is fine. For a contract, a scan of an ID, or anything personal, add some protection:
- Password. The code gets them to the transfer; the password gets them the file. Send the password a different way than the code, for example code by phone and password by text. See password-protected file sharing.
- Download limit. Set it to 1 if only one person should download. Options are 1, 5, 10, 50 or 100.
- Short expiry. If the receiver is standing next to you, choose 1 hour.
- Delete it yourself. Once they confirm they have the file, delete the transfer.
Enzonic Send encrypts files in transit and at rest, but it is not end-to-end encrypted. The password and limits are the practical controls you have.
When the code does not work
Work through these in order:
- Check the digits. Ask the sender to read them again slowly. Transposed numbers are the most common problem.
- Check the expiry. If it was set to 1 hour and the hour is up, the transfer is gone. The sender needs to upload again.
- Check the download limit. If the limit was 1 and someone already downloaded it, it will not be available again.
- Check that it was not deleted. The sender may have removed it after the first download.
- Check the page. The code goes on send.enzonic.com/receive, not on the home page uploader.
Size limits apply to the transfer, not the code
The code works the same whatever you send. The size limits are per transfer: up to 500 MB without an account, up to 2 GB with a free account. If you send several files or a folder, they are zipped in your browser into one archive, and the whole archive gets one code. That makes the code approach handy for sending multiple files to someone who would otherwise get a list of separate links.
FAQ
How long does a 6-digit code work?
As long as the transfer exists: 1 hour, 1 day or 3 days without an account, up to 7 days with a free account. It stops working when the transfer expires or you delete it.
Do both devices need to be online at the same time?
No. Files are stored on Cloudflare's network, so you can upload, close the tab, and the receiver can enter the code later, as long as it has not expired.
Where does the receiver type the code?
At send.enzonic.com/receive in any browser, or in the Enzonic Send app for Android and iOS.
Can someone guess my code?
A short code is easier to guess than a long link. For anything sensitive, add a password and a download limit, and pick a short expiry.
Is the code different from the share link?
They point to the same transfer. The link is for clicking, the code is for typing, and the QR code is for scanning.
