WhatsApp Link Generator — Create Your Free wa.me Link

How to use the WhatsApp link generator

Select the country code (Brazil, +55, comes pre-selected), type the number with the area code using digits only and, if you want, write the pre-filled message that should appear already typed for whoever clicks. The link is built in real time: check the preview, click Copy link and paste it into your bio, website or ad. The Open in WhatsApp button lets you test the result before sharing — do this at least once to make sure the number is right.

The tool validates the number as you type: for Brazil, it checks the area code and warns when the mobile ninth digit seems to be missing — the most common mistake behind broken WhatsApp links. And everything happens in your browser: neither the number nor the message is sent to any server.

Anatomy of the wa.me link

The official format is https://wa.me/<number>?text=<message>. The number must be in full international format: country code + area code + number, all together and without the + sign, carrier zeros, dashes, parentheses or spaces. A mobile number in São Paulo, for example, becomes wa.me/5511912345678 — 55 for Brazil, 11 for the area code and the 9 digits of the number. The ?text= parameter is optional and carries the message URL-encoded (spaces become %20, accented characters become sequences like %C3%A1) — the tool does this encoding automatically, so write your text normally, with accents and line breaks.

The mistakes that most often break links are: repeating the 55 (the code already identifies Brazil), forgetting the area code, omitting the mobile ninth digit and pasting the number formatted with dashes. If the link opens WhatsApp but shows “the phone number shared via url is invalid”, the problem is in one of these points.

Pre-filled message best practices

The pre-filled message exists to reduce friction, not to sell on the first tap. The ones that convert best are short and give context of origin: “Hi! I saw your website and would like a quote” says where the person came from and what they want — and it doubles as informal tracking when you use a different message per channel. Avoid walls of text, lists of questions and anything that sounds like spam: whoever clicks wants to talk, not to receive a form. Remember the person can (and will) edit the text before sending; treat the message as an icebreaker, not a contract.

Keep an eye on the character counter: above ~1,800 characters, the resulting URL gets so long that social networks, email clients and QR code readers may cut it in half, breaking the link. If you need that much context, send the person to a page on your website and leave WhatsApp for the conversation.

Use cases for businesses and devs

For businesses, the WhatsApp link is the shortcut between attention and conversation: Instagram bio, click-to-WhatsApp ad buttons, email signatures, QR codes at the counter and PDF catalogs. Each channel can have its own pre-filled message, which makes it easy to know where the contact came from without relying on UTM — which WhatsApp does not pass along.

For devs, the same link works as a deep link: use it in the href of a floating website button (the classic green bubble in the corner of the screen), in an <a> with target="_blank" and rel="noopener", or inside mobile apps — Android and iOS open the WhatsApp app automatically when it is installed, and the browser falls back to WhatsApp Web. Since the URL is just text, you can generate it dynamically on the backend or the frontend (an encodeURIComponent handles the message) and use it in scheduling systems, e-commerce and thank-you pages.
