What is a WhatsApp link?
A WhatsApp link (also called a click-to-chat link or wa.me link) is a normal web address that opens a WhatsApp conversation with a specific number. Whoever taps it doesn't need to save your contact first: the chat opens straight away, on their phone or in WhatsApp Web on a computer.
The official format is https://wa.me/ followed by the full number in international format — country code included, without the plus sign, zeros, spaces or dashes. For a Portuguese number that is https://wa.me/351912345678; for a number in Brazil, https://wa.me/5511912345678. Add ?text= and a URL-encoded message and WhatsApp writes that message in the chat box for the visitor.
Why use a link with a pre-filled message
The first message is the hardest one to send. A ready-made message removes that friction: the visitor taps, sees a sensible sentence already written, and presses send. Businesses that answer on WhatsApp typically get more conversations this way than with a bare number.
It also tells you where each chat came from. Use a different message per channel — "Hi, I found you on Instagram" in your bio, "Hi, I'd like to book" on your booking page — and you know which one works without any tracking software.
Where to use your WhatsApp link
In your Instagram and TikTok bio, where only one link fits — which is why most creators and businesses put a link-in-bio page there and the WhatsApp button inside it.
In your Google Business Profile, email signature, website, online ads and replies to customers. And printed, as a QR code, on business cards, menus, receipts, product labels and shop windows: people point their camera and the chat opens.
WhatsApp Business, groups and privacy
The same link works for personal WhatsApp and for WhatsApp Business accounts; nothing changes in the format. Group invitations are different: they use chat.whatsapp.com links created inside the group, not a phone number.
This generator runs entirely in your browser. Your number and your message are not sent to our servers to build the link or the QR code. Keep in mind that anyone who has the link can see the number it points to — that is how WhatsApp links work.
