Error correction

Higher levels survive more damage and make the code denser. M is the usual choice; use H only if the code will be printed small or partly covered.

What the code actually contains

https://wa.me/?text=

Builds a `wa.me` link and encodes it. Scanning opens WhatsApp with a chat to your number and an optional message already typed but not sent.

How to make a whatsapp qr code

1 Fill in the fields. The code updates as you type.

2 Raise the error correction if it will be printed small or might get covered.

3 Download it as PNG for the web or SVG for print — SVG stays sharp at any size.

The number format is the thing that goes wrong: `wa.me` wants the full international number with no plus sign, no spaces, no dashes and no leading zero. A Dutch mobile written 06 12 34 56 78 becomes 31612345678. Get that wrong and the link opens WhatsApp with an error rather than a chat. Worth knowing that the message is pre-filled and not sent — the person still taps send, which is what makes this useful for support and ordering flows rather than intrusive. This works for any WhatsApp account; it does not require a Business account.
