QR Code Generator

Generate a QR code for a URL, text, email, phone number, SMS, or a contact card (vCard), with the size and error correction level you need. Download it as PNG or SVG.

What each option is for

Size and margin only affect how the QR looks (bigger, more margin around it). Error correction is different: the higher it is, the more physical damage (a torn corner, a smudge) the printed code can take without losing readability — in exchange, the QR pattern itself gets a bit denser.

What can be encoded

Beyond a URL or free text, the Email, Phone, SMS and Contact (vCard) modes generate the special format every QR reader recognizes automatically: scanning them, the phone offers to open the email, make the call, send the SMS, or save the contact directly — not just plain text to copy.

If you need a QR that connects automatically to a WiFi network, use the dedicated WiFi QR tool, which generates the special format that case needs.
