WhatsApp QR code
Put it on a shop window, a flyer or an invoice: the customer scans, WhatsApp opens on your number, and the message you prepared is already in the box. They only press send.

Loading the tool…
How it works
- Enter your number with the country code, and optionally the message you want pre-filled.
- Adjust the size, colours and error correction if you need to.
- Download it as PNG for print, or SVG to scale it to any size.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
Do I need WhatsApp Business?
No. This builds a standard wa.me link, which works with any WhatsApp account. The country code is the part people get wrong — it must be there, and without the leading zero of the local format.
Can I edit this code later, or see how many people scanned it?
No, and that is deliberate. The code contains your data directly, so it keeps working forever and cannot be switched off. Services offering editable codes and scan counts do it by pointing the code at their own server first — which also means the code dies the day they do, or the day the free tier ends.
Is anything uploaded?
No. A QR code is your text turned into a pattern, and that happens in this tab. Nothing is sent anywhere — which matters most for the types carrying a Wi-Fi password or a private phone number.
What size should I print it?
A rough rule: the code should be at least a tenth of the distance it is scanned from. Read at arm’s length, two centimetres is enough; on a poster read from three metres, aim for thirty. Leave the light margin around it — scanners need it to find the code.
