How to create a QR code
- Choose what the QR should contain: a link or text, a Wi-Fi network or a WhatsApp chat.
- Fill in the details. The QR updates as you type.
- Optionally change the size, colors and error correction.
- Download it as PNG (for sharing and printing) or SVG (for scaling without losing quality).
What is this tool for?
A QR code lets people open a link, join your Wi-Fi or message you on WhatsApp just by pointing their camera. It is handy for menus, business cards, posters, product labels, Wi-Fi at home or at your business, and event invitations.
These QR codes are static: the information is written into the code itself, so they never expire and do not depend on any service. Everything is created on your device, so passwords and private links are not uploaded.
Limits to keep in mind
- The more text, the denser and harder to scan the code; keep links short.
- Keep strong contrast and dark color on a light background. Inverted codes fail on many scanners.
- Higher error correction makes the code more tolerant to damage but also denser. Medium is right for most uses.
Frequently asked questions
Is the QR code free, and does it expire?
It is free, and it never expires: the QR is static, with the data written in the code itself. It does not depend on our site.
How do I make a free QR code for a link?
Paste the link into the Text or link box and the QR code appears right away. Download it as a PNG for screens or as an SVG to print at any size.
Is what I type sent to a server?
No. The QR is generated in your browser. Links, passwords and messages are not uploaded or stored.
What is the difference between PNG and SVG?
PNG is an image that works everywhere. SVG is vector: it scales to any size without blurring, which is ideal for printing large.
How do I make a QR for my Wi-Fi?
Choose Wi-Fi, enter the network name and password, and pick the security type (usually WPA). Phones can join by scanning it.
Can I print it small?
Yes, but not too small: about 2 cm per side is a safe minimum for short links. Always test it with your phone before printing.
