How to create a WhatsApp QR code for free

If you run a business, work as a freelancer, or simply want people to message you without having to spell out your number, a WhatsApp QR code is one of the most practical things you can set up today. The process takes about two minutes, costs nothing, and requires no sign-up or app installation.

This guide walks you through exactly how to do it, which link formats to use, and where you can put your QR code once it's ready.

What is a WhatsApp QR code and why does it matter?

A WhatsApp QR code is a QR that, when scanned with a phone camera, opens a WhatsApp chat with your number directly — no need for the other person to save your contact or type your number. They scan it, tap Send, and they're talking to you.

It's especially useful for:

• Businesses that want to make contact easy on signs, windows or menus
• Business cards where space is limited
• Online stores offering WhatsApp support
• Social media bios, Instagram links or email signatures
• Events, trade shows or conferences where you hand out printed material

Step 1: generate your WhatsApp link

WhatsApp has an official link format called wa.me that opens a chat directly. The basic structure is:

Where 1 is the country code for the US/Canada and XXXXXXXXXX is your phone number with no spaces or dashes. For the UK use 44, for Australia 61, for India 91.

Real examples:

• US: https://wa.me/12125551234
• UK: https://wa.me/447911123456
• Australia: https://wa.me/61412345678

Optional: add a pre-filled message

If you want the chat to open with a message already typed, add the ?text= parameter to your link. This is great for guiding customers or saving them time:

Spaces become %20 and commas become %2C. For longer messages, use a URL encoder to convert the text.

Step 2: turn the link into a QR code

Once you have your wa.me link, the rest takes seconds:

1. Go to Herramientapp's QR Generator
2. Paste your full wa.me link into the text field
3. The QR generates automatically in real time
4. Click Download PNG and the file saves to your device

Everything happens in your browser — your link is never sent to any server and the QR never expires. You can generate as many as you need with no limits.

Step 3: use your QR wherever you need it

The downloaded PNG is high resolution and ready for:

• Print: business cards, posters, flyers, menus, product labels
• Digital: Instagram bio (via tools like Linktree), email signature, website, slide decks
• Social media: Facebook posts, Instagram stories, LinkedIn profile

Does it work with WhatsApp Business?

Yes. The wa.me link works identically with WhatsApp Business numbers. If you use WhatsApp Business, you can also set up your product catalog and welcome messages inside the app — but an external QR code is still the easiest way to capture contacts from printed or digital material.

wa.me QR vs. the native WhatsApp QR

WhatsApp has its own QR code inside the app (Settings → profile → QR icon). The key difference is that this QR can expire if you regenerate it or change certain settings. A QR based on a wa.me link, by contrast, never expires as long as your number is active — making it safe to print at scale.
