What is a WhatsApp chat widget?
A WhatsApp chat widget is a floating button - usually placed in the bottom corner of a website - that opens a WhatsApp conversation with your business the moment a visitor clicks it. It works the same way on desktop and mobile, and needs no login or install on the visitor's side.
Unlike a plain text link, a widget stays visible as visitors scroll and browse your site, giving them a constant, low-friction way to reach out - which is why it is one of the most common conversion tools on service, e-commerce, and SaaS websites.
How to add the WhatsApp widget to your site
Enter your WhatsApp number
Pick a country and add the number you want customer chats to land on.
Customize the widget
Set your brand color, button position, business name, and a welcome message.
Copy the code snippet
Grab the ready-to-use HTML/JS snippet - no libraries or dependencies required.
Paste it on your site
Drop it right before the closing </body> tag of any page and the button appears instantly.
Why add a WhatsApp widget to your website
A visible, always-on WhatsApp button turns passive website visitors into real conversations on the channel most of your customers already check every day.
- Lower friction than a contact form - one tap opens a chat instead of filling fields
- Stays visible while visitors browse, unlike a link buried in the footer
- Matches your brand color and greeting message out of the box
- Works on any platform that accepts custom HTML - WordPress, Shopify, Wix, or hand-built sites
- No dependencies, tracking scripts, or account sign-up required to use it
Frequently asked questions
What is a WhatsApp chat widget?
A WhatsApp chat widget is a floating button, usually in a bottom corner of a website, that opens a WhatsApp conversation with your business when clicked. It works on desktop and mobile and requires no account or backend - just a wa.me link wrapped in a small UI.
Do I need to install anything to use this?
No. The generated snippet is plain HTML, CSS, and vanilla JavaScript with zero external dependencies. Paste it once into your site template (or every page you want the button on) and it works immediately.
Will this work on WordPress, Shopify, Wix, or a custom site?
Yes. Since it is a self-contained snippet, you can add it via a custom HTML/embed block, theme footer file, or tag manager on any platform that lets you insert custom HTML or JavaScript.
Can I change the color, position, or message later?
Yes - just come back to this generator, adjust the fields, and copy the new snippet to replace the old one on your site.
Is this WhatsApp Widget Generator free?
Yes, completely free with no sign-up. It runs entirely in your browser and does not store the numbers or messages you configure.
