Details of each setting

What each field means and how to use it. Click to expand.

Recipient email address

The destination address (e.g. info@example.com). This tool supports a single recipient. To reach several inboxes, explain that in the body text instead.

Subject and body

The subject and body pre-filled into the compose screen when the QR is scanned. Add a template message so people can just press send. Subject and body are URL-encoded into the QR string. Both can be blank.

About the mailto format

This tool builds the QR from the widely supported mailto:address?subject=...&body=... format. Behavior varies by device and mail app; on most it only opens a compose screen with everything pre-filled, and the user must press send.

Error correction / size / margin

Error correction is how much of a damaged code can be recovered (L≈7%, M≈15%, Q≈25%, H≈30%). Size is the PNG side length; margin is the white border (4+ recommended). A long body makes the QR denser, so for print keep error correction moderate and use a larger size.

Frequently asked questions (FAQ)

What is an email QR code?

An email QR code bundles a recipient address, subject and body into a single QR code. Scanning it with a smartphone opens a pre-filled compose screen, so you can add an inquiry path to business cards, flyers and posters.

Does scanning send the email automatically?

No. On most devices it only opens a compose screen with everything pre-filled; the user still presses send. Behavior varies by device and mail app. It never sends on its own.

Is my address and message safe?

Yes. Everything from entering the address, subject and body to generating and downloading the QR code runs entirely in your browser (JavaScript). Your input is never sent to any server.
