Free WhatsApp QR Code Generator | Scan to Chat


A QR code can make it much easier for customers, clients, friends, or event attendees to start a WhatsApp conversation. Instead of typing or saving a phone number manually, someone can scan a QR code and open a WhatsApp chat from their smartphone.

This can be particularly useful for businesses that want customers to contact them quickly about products, services, bookings, questions, orders, or support.

Quick Answer: How Do You Create a QR Code for WhatsApp?

First, create a WhatsApp Click to Chat link using the phone number in international format. Then turn that URL into a QR code using a URL QR Code Generator.

The basic WhatsApp link format is:

https://wa.me/1234567890

Replace the example number with the full WhatsApp phone number in international format.

WhatsApp's official guidance says the phone number in a Click to Chat link should be in international format without leading zeros, plus signs, parentheses, or hyphens. 

What Is a WhatsApp QR Code?

A WhatsApp QR code is a QR code that contains a WhatsApp chat link. When someone scans it, the link can open a WhatsApp conversation with the specified number.

The QR code itself does not replace the WhatsApp account. It simply provides a convenient way to access the WhatsApp link.

WhatsApp's Click to Chat feature allows people to start a conversation without first saving the phone number in their address book, provided the number has an active WhatsApp account.

How to Create a WhatsApp Link

Step 1: Get the WhatsApp Phone Number

Start with the phone number associated with the WhatsApp account you want people to contact.

Use the complete international phone number, including the country code.

Step 2: Remove Unnecessary Characters

For the WhatsApp Click to Chat URL, remove the plus sign, spaces, parentheses, hyphens, and other formatting characters from the number.

For example, a number displayed as:

+1 (555) 123-4567

would be represented in the link as:

https://wa.me/15551234567

This follows WhatsApp's documented Click to Chat format. 

Step 3: Create the WhatsApp Link

Use this format:

https://wa.me/<internationalphonenumber>

For example:

https://wa.me/15551234567

Before using the link, check that the country code and phone number are correct. The number must belong to an active WhatsApp account. Open the link on a phone and confirm that it directs you to the intended conversation before generating or printing the QR code.

2. Open the URL QR Code Generator

Open our URL QR Code Generator .

3. Paste Your WhatsApp Link

Paste the complete https://wa.me/... URL into the URL field.

4. Generate the QR Code

5. Download the QR Code

Download the QR code in a suitable format for your intended use.

6. Scan-Test It

Before printing or publishing the QR code, scan it with a smartphone and confirm that it opens the intended WhatsApp conversation.

How Does a WhatsApp QR Code Work?

The process is simple:

  1. A business or individual creates a WhatsApp Click to Chat link.
  2. The WhatsApp link is converted into a QR code.
  3. The QR code is printed or displayed digitally.
  4. A person scans the QR code with a compatible smartphone.
  5. The WhatsApp link opens and the person can continue to the chat.

The QR code is therefore acting as a visual shortcut to the WhatsApp link.

Can You Add a Pre-Filled WhatsApp Message?

Yes. WhatsApp's Click to Chat links can include an optional URL-encoded message that appears automatically in the chat's message field. 

The general format is:

https://wa.me/15551234567?text=Hello%20I%20would%20like%20more%20information

The message must be URL encoded. Spaces, for example, are represented as %20.

Example: Product Inquiry

https://wa.me/15551234567?text=Hello%20I%20would%20like%20to%20know%20more%20about%20your%20product

Example: Appointment Request

https://wa.me/15551234567?text=Hello%20I%20would%20like%20to%20book%20an%20appointment

Using a pre-filled message can help businesses give customers a clear starting point for a conversation. WhatsApp documents this feature as part of Click to Chat. 

A pre-filled message is a suggestion for the person scanning the QR code; it is not sent automatically. The person can review, edit, or delete the message before choosing to send it. Keep the suggested message relevant and avoid including private or sensitive information in the link.

Always test the printed QR code before ordering a large quantity of business cards.

WhatsApp QR Code for a Website

You can also place a WhatsApp QR code on a website for visitors who are viewing the site on another device or want a convenient way to start a conversation from a printed or secondary screen.

For a website viewed directly on a smartphone, a normal WhatsApp link or button may be more convenient. A QR code is especially useful when the customer is viewing your information on paper, a desktop screen, signage, packaging, or another device.

How to Make a WhatsApp QR Code Easy to Scan

Use Good Contrast

Keep the QR pattern clearly visible against its background. Strong contrast generally makes scanning easier.

Leave Enough White Space

Avoid placing text, logos, borders, or decorative elements too close to the QR code.

Choose an Appropriate Size

The QR code should be large enough for the intended scanning distance. A code printed on a small business card may need a different size from one displayed on a poster.

Test the Final Version

Always test the exact QR code you intend to publish or print.

Common WhatsApp QR Code Mistakes

  • Using the wrong country code.
  • Leaving a leading zero in the international WhatsApp URL.
  • Including a plus sign in the phone number portion of the URL.
  • Including spaces or hyphens in the phone number portion.
  • Using a phone number that does not have an active WhatsApp account.
  • Not testing the QR code before printing it.
  • Making the QR code too small.
  • Using poor contrast.
  • Adding excessive decoration around the QR code.
  • Using a pre-filled message without properly URL-encoding it.

WhatsApp QR Code Testing Checklist

  • ✓ The phone number is correct.
  • ✓ The country code is correct.
  • ✓ The number is in international format.
  • ✓ Unnecessary formatting characters have been removed.
  • ✓ The WhatsApp account is active.
  • ✓ The QR code scans correctly.
  • ✓ The intended WhatsApp chat opens.
  • ✓ Any pre-filled message appears correctly.
  • ✓ The QR code is large enough for its intended use.
  • ✓ The final printed or displayed version has been tested.

Privacy and Contact Considerations

A WhatsApp QR code makes it easier for people to initiate contact, so businesses and individuals should consider where and how they display it.

Only publish a phone number or WhatsApp contact link that you are authorized to share. If the QR code is intended for a business, use the appropriate business contact number.

Consider where the QR code will be displayed and who may scan it. For a business, use a contact number intended for customer enquiries rather than publishing a personal number unnecessarily. If you use the QR code for customer support or marketing, explain how customers can contact you and avoid sending unsolicited promotional messages.
