WhatsApp link generator (wa.me) with message and QR code

How a wa.me link works

WhatsApp accepts links in the form https://wa.me/<number>. Tapping one opens a chat with that number without saving it as a contact first. Add ?text= followed by a message and the typing box opens pre-filled — the person only has to tap send, and can edit the text first.

The number in international format

The link only works with the number in international format, digits only: country code, area code and number, with no +, spaces, brackets or dashes. Brazil's country code is 55, and Brazilian area codes are called DDD (two digits). The tool cleans the number for you:

1. it strips everything that isn't a digit (spaces, brackets, dashes, the + sign);
2. if the number starts with 00 (the international dialling prefix), those two zeros are removed;
3. if what remains has 11 digits or fewer — the length of a Brazilian national number with DDD — and does not already start with the country code, it adds 55 in front.

So (41) 99876-5432, 41 99876-5432 and +55 41 99876-5432 all become 5541998765432. Type only the DDD and the number: a leading zero or carrier code before the DDD (as in 0xx41, a habit from Brazilian long-distance dialling) makes the number too long and is not removed automatically. Brazilian numbers are checked: after 55 there must be a two-digit DDD (no zeros) and an 8- or 9-digit number. For other countries, change the country code and enter the full number.

The encoded message

A URL cannot contain spaces or certain loose characters, so the message goes through URL encoding (the browser's encodeURIComponent function): a space becomes %20, é becomes %C3%A9, a line break becomes %0A. Accents and emojis work fine; WhatsApp decodes everything when the chat opens. Spaces at the start and end of the message are trimmed, and if the message ends up empty the link is produced without ?text=.

The QR code

The QR code is generated in your own browser from the final link — nothing is sent to our server or to third-party services. Scanning it with a phone camera opens the same chat as the link. The longer the message, the denser the pattern; for print, keep the message short and print the code at least 2–3 cm (about 1 inch) wide.

Where to use it

• Instagram, TikTok or other social media bios;
• e-mail signatures and your website's contact page;
• menus, business cards, window stickers and packaging (with the QR code);
• ads and campaigns, with a different message per channel so you know where each contact came from.

If you want a button pinned to the corner of your website, use the WhatsApp button generator for websites, which builds ready-to-paste code with this same link.

A bakery in Curitiba uses the fictitious number +55 41 99876-5432 and wants customers to arrive already asking for a quote. In the number field you can simply type (41) 99876-5432: the tool strips the brackets, space and dash and adds 55, giving 5541998765432. The message is “Hi! I saw your website and would like a quote.”. After encoding, each space becomes %20 while the exclamation mark and full stop stay as they are. The final link is https://wa.me/5541998765432?text=Hi!%20I%20saw%20your%20website%20and%20would%20like%20a%20quote. — ready to copy, test on your phone and turn into a QR code for the counter.
