How to make a free QR code
QR codes are one of the fastest and easiest ways to share almost any kind of information — from simple links to Wi-Fi passwords and contact cards. Whether you want to connect with people, promote something, or simplify access to your services, QR codes let others scan and instantly act.
Yohn.io offers a variety of free QR code generators for different purposes. Here’s how it works and how to choose the right generator for your needs.
Step 1: Choose the Right QR Code Generator
Go to Yohn.io’s free QR code generator tool — in the green section there you’ll find the links to all available QR code generators. Select the one that matches what you want to create:
Link to QR
Turn any website or URL into a scannable QR code.
Text to QR
Convert plain text (messages, instructions, notes) into a QR code.
vCard to QR
Create a digital business card. When scanned, it opens a contact preview and allows the user to instantly save your name, phone, email, and more — no typing required.
Email to QR
Pre-fill an email draft. When scanned, the user’s mail app opens with the recipient, subject, and message already filled in.
SMS to QR
Generate a QR code that opens the messaging app with a pre-written text message.
Wi-Fi to QR
Share your Wi-Fi network. When scanned, it automatically connects the user to your Wi-Fi (no password typing needed).
Bitcoin to QR
Share a crypto wallet address for Bitcoin, Bitcoin Cash, Ethereum, Litecoin or Dash — perfect for tips, payments, or donations.
Twitter to QR
Direct people to your Twitter/X profile, post, or hashtag.
Facebook to QR
Share your Facebook profile, page, or group with a scannable code.

- Fill in the required fields (e.g. URL, contact details, Wi-Fi credentials, etc.).
- Enter your email address to receive your QR code.
- Agree to the terms if prompted.
Step 3: Click “Generate” and Check Your Inbox
