Create a prefilled email QR code

For shops, teams and individuals sharing information in one scan, this generator prepares a practical handoff. Prepare an email QR code with the recipient and subject filled in.

Prepare an email QR code with the recipient and subject filled in. Check the preview and download a scan-ready code without creating an account.

How to use

Enter the recipient address that should appear when someone scans the code.
Write a clear subject line, then add the message body if you want part of the email filled in.
Set the visual footprint by picking 256 px, 512 px or 768 px according to the available space.
For tolerance to damage, compare the M, Q and H settings before validating, since a higher level makes the pattern denser.
Create the image, open it with a phone to check the prepared email, then save the file.

Example

A support team puts a QR code on a product card. When a customer scans it, the phone prepares an email addressed to support with the subject and an opening message. The team tests the code on several phones before sending the card to print.

Limits and formats

The scan opens an email draft in the phone app; it never sends the message for the user.
Results vary by email application, because some apps may ignore the subject or body text.
A wrong recipient address sends the message to the wrong contact, so check it before distributing the code.
A high correction level makes the pattern denser, which can reduce readability on very small labels.

Where processing happens

The email QR image is built inside your browser. The recipient, subject and message stay on your device while the code is generated, with no account required.

Frequently asked questions

Will scanning the code send the email right away?

No, it opens a draft in the phone s email app. The person scanning still has to review the message and press send. This extra step prevents an email from being sent without the user s confirmation.

Can I leave the message body empty?

Yes, you can prepare only the recipient and subject. The scan will then open a shorter draft that the sender can complete. Test the result on a phone to see how the user s email app handles fields left blank.

Why does the subject not appear for some users?

Email apps do not all handle prefilled information in the same way. Some may ignore the subject or part of the body. Write the message so it still makes sense if only the recipient address appears after scanning.
