Email QR Code Generator

Encode a mailto address, subject, and body locally and export the QR code as PNG or SVG.

Encoded payload

ReadyEncodes a standard mailto URI; scanning normally opens the device email app.

Generate the payload, then proof the actual symbol geometry

A valid payload is only one layer. Compare the rendered QR's module count, raster detail and intended physical size before you commit to print, labels or distribution.

Standards and assignment boundary

Use the exact symbology required by the receiving system. WebToolArc can validate supported syntax and check digits, but it does not allocate GS1 identifiers, certify regulated documents, or guarantee acceptance by a particular scanner, retailer, carrier, or institution.

Mailto semantics

The QR stores a mailto URI. It can prefill recipient, subject, and body, but sending still requires a configured mail app and the user must review the draft.

Email QR checks that matter before printing

Keep the mailto payload short enough to scan

Recipient, subject, and body all increase QR density. A concise subject and a short structured body usually scan more reliably than a long paragraph, especially on small printed labels. Use the payload length and symbol geometry already shown above before committing to a print run.

Proof the exported file, not only the browser preview

A code that looks good on screen can fail after scaling, compression, lamination, or low-contrast printing. Test the exact exported PNG or SVG on at least one iPhone and one Android device at the intended physical size and viewing distance.

Remember that scanning opens a draft

A mailto QR code does not send mail automatically. The scanner opens the user’s mail app with fields prefilled, and the user still chooses whether to send. This is useful for support, feedback, and forms where the sender should retain control.
