Free tool
Free WhatsApp link and QR code generator
Let customers start a WhatsApp chat with you in one tap or scan, without saving your number first. No sign-up, and nothing you type leaves your browser.
Customers can edit it before sending. Up to 300 characters, in any language.
Your number and message are not sent to Criza Labs. Anyone who has the link or scans the code can see both, so include only what you are happy to make public.
Your link and QR code
Enter your WhatsApp number and they will appear here.
Where to use it
- On a printed card or sign at your counter
- On visiting cards, packaging, bills and pamphlets
- In your Instagram or Facebook bio
- On your website's contact button
- In your Google Business Profile, where a link field fits
How it works
- Enter the number that has WhatsApp on it.
- Add a first message, if you want one.
- Test the link and scan the code on your phone.
- Copy the link or download the QR code, and use it wherever customers find you.
Frequently asked questions
Is this WhatsApp link generator free?
Yes. It is free, with no sign-up and no limit on how many you make. The link and QR code are yours to use, including on printed and commercial material.
Does the link or QR code expire?
We set no expiry, and the code does not pass through our website. It points directly to a WhatsApp click to chat address, so it depends on WhatsApp's service and on your number staying active on WhatsApp.
Does Criza Labs see or save my number?
No. The link and code are created in your browser, and what you type is not sent to us or saved by this tool. If you use the link elsewhere, the services you use it with can see it, like any other link.
Does it work with the WhatsApp Business app?
It uses WhatsApp's standard click to chat format, which takes the number's full international form. The number must be registered on WhatsApp, so test it on your phone before you share it.
What size should I print the QR code?
It depends on the scanning distance and on how long your message is. Keep the white border around the code, print one sample, and test it from where a customer would stand before printing many copies.
Can I message customers in bulk with this?
No. This tool only lets customers start a chat with you. Sending messages to many people is a separate matter with its own permission rules, which our WhatsApp guide explains.
