WhatsApp tools

Link or button?

In Brazil, WhatsApp is the main customer channel for countless shops, clinics and service providers. Yet the path to a conversation often has friction: the customer has to copy the number, save the contact, open the app and think of what to write. The two tools here shorten that path to a single tap.

The WhatsApp link generator creates a wa.me address that opens a chat straight to your number, with an opening message already typed if you want one. It also produces a QR code. Use the link wherever only text fits — an Instagram bio, an e-mail signature, an ad, a message to customers — and the QR code in the physical world: menus, business cards, shop windows, packaging.

The WhatsApp button generator uses the same link and builds a small HTML and CSS snippet that shows a button pinned to the corner of the screen. Use it when you have a website and want contact to be one tap away on every page, without visitors having to look for it.

Three details that make a difference

• Number in the right format. The link needs the international number as digits only: country code, area code and number (for Brazil, 55 followed by the two-digit DDD). The tools strip spaces, brackets and dashes and add 55 automatically, but enter only area code and number, with no leading zero or carrier code.
• A short, useful message. One sentence that states the topic (“I'd like a quote for a cake”) helps you reply faster and also tells you where the customer came from. Different messages for Instagram, the website and the menu act as a simple source tag.
• Test before publishing. Open the link on a phone other than yours and check that the chat goes to the right number. For the QR code, print a proof and scan it with more than one device.

Lightweight and private

Both tools run entirely in your browser: the number and message you type are not sent to our server, and the QR code is drawn locally too. The generated button loads no third-party script, so it does not slow your site down or set cookies on your visitors — it is a styled link you can edit as you like.

You do not need a WhatsApp Business account or API access: the public wa.me link works with any number registered on WhatsApp. This site is not affiliated with WhatsApp or Meta. WhatsApp is a trademark of WhatsApp LLC.
