About the QR Code Generator
QR codes turn any URL, text string, or contact detail into a scannable square that phones read instantly. Restaurants use them for menus, marketers put them on flyers, developers embed them in test builds, and event organizers print them on tickets.
Making a QR code is straightforward — you provide the content, pick a size and color, and download a PNG. The code itself is just a visual representation of your data; scanning it opens the URL, displays the text, or triggers whatever action you encoded.
This generator creates codes entirely in your browser using canvas rendering. No data is sent to a server, so you can encode internal staging URLs, private contact cards, or WiFi credentials without them being logged anywhere. Download the PNG and use it in print materials, slides, or app mockups.
How to Generate a QR Code
- Enter the content you want to encode — a URL, plain text, phone number, or other supported format.
- Adjust size and colors if customization options are available. Dark-on-light gives the most reliable scans.
- Preview the QR code on screen and test it with your phone camera before downloading.
- Click Download to save the QR code as a PNG image for print or digital use.
Common Questions
Answers to what people usually ask about qr code generator
Do QR codes expire?+
Static QR codes (like the ones this tool generates) never expire — they encode the data directly. Dynamic QR codes routed through a third-party service can expire if you stop paying for the service. Our codes are static and permanent.
What is the maximum data length?+
QR codes can hold up to about 4,000 alphanumeric characters, but longer content produces denser codes that are harder to scan. For URLs, keep them short. Use a URL shortener first if your link is very long.
Can I use the QR code commercially?+
Yes. QR codes themselves are an open standard with no licensing fee. You can print them on products, marketing materials, and packaging without restriction.
