About QR Code Generator

Error correction is the setting worth understanding: higher levels rebuild a code that is partly obscured or scuffed, at the cost of a denser pattern. Raise it for anything printed on a label that will take wear, keep it low for clean on-screen display.

Make a QR code that, when scanned, opens the messaging app with the number and message pre-filled — great for feedback lines, campaigns and support. The code is built entirely in your browser.

Generate scannable QR codes for links, WiFi networks, contact cards (vCard), SMS messages and email, then fine-tune the size, foreground and background colours and error-correction level before exporting a crisp PNG or vector SVG. A WiFi QR lets guests join your network with one scan; a vCard QR drops your contact details straight into a phone; a URL QR bridges print and web.

Higher error-correction levels add redundancy so a code still scans when part of it is dirty, printed small or covered by a logo. The image also encodes your value directly rather than pointing at a shortener, so it keeps working indefinitely — there is no redirect to expire, break or start charging.

Frequently asked questions

What does an SMS QR code actually do?

Scanning it opens the phone's messaging app with the recipient number and message body already filled in. It does not send anything — the person still has to press send, which is what makes it usable for opt-in flows.

How should I format the phone number?

Use full international format with the country code — `+441632960123` — so it works regardless of where the person scanning is. A local-format number will fail for anyone outside that country.

Is there a length limit on the message?

No hard limit, but longer text makes a denser, harder-to-scan code, and a long pre-filled message is more likely to be edited or abandoned. Short keyword-style bodies work best.
