About this qr code generator
The QR code generator turns a link or any text you paste into a scannable QR code you can download as a PNG. It encodes exactly what you type, so as well as a plain URL you can paste a formatted string yourself — a vCard for contacts, a WIFI: string for network details, or a tel: or mailto: link — and customize the colors, size, and margin.
A QR code is only as useful as where it points and how well it scans, so it pays to keep the content short and the image crisp. Test the finished code with a phone before printing, and use a short, stable destination so the code keeps working once it is out in the world.
Common uses
- Create a QR code that opens a website, then download it as a PNG for print or screen.
- Paste a vCard, WIFI: string, tel:, or mailto: link to encode contact, network, or message details.
- Generate a code for a poster, flyer, menu, or business card.
Helpful tips
- Use a dark code on a light background with a clear margin for the most reliable scans.
- Test the final code with more than one phone before printing it at scale.
- Point to a short, stable URL so the code keeps working if the destination changes.

Frequently asked questions
What can a QR code contain?
Any short text you paste. For a plain link just type the URL; for contacts, Wi-Fi, phone, or email you paste the standard string yourself (such as a vCard, a WIFI: string, or a tel:/mailto: link). Keep it concise so the code stays easy to scan.
How do I make a QR code easier to scan?
Use strong contrast, leave a quiet margin around the code, print it large enough, and test it with a phone before sharing it widely.
