About this QR Code Generator
The QR Code Generator builds standard QR codes client-side for plain URLs and text, WiFi network credentials (network name, password, and encryption type encoded so a phone camera can join automatically), and vCard contact cards that add a contact entry when scanned. Each code is rendered at your chosen size and downloadable as a PNG.
QR codes include a selectable error-correction level, which trades data capacity for damage tolerance: a higher level keeps the code scannable even if part of it is scuffed, covered by a logo, or printed slightly blurry, which matters more for a code that will live on a poster or product label than one that only appears on a screen. Before printing anything at volume, scan the generated code with a couple of different phone cameras to confirm it reads correctly at the size you intend to print.
Generation happens entirely offline in your browser once the page has loaded, so URLs, WiFi passwords, and contact details never pass through our servers. This makes it a fast option for one-off needs like a WiFi password card for guests, a link on a printed flyer or business card, or a check-in code for a small event — anywhere a scan should replace typing a URL by hand.
Our QR Code Generator is completely free to use with no signup required. For this tool, processing runs in your browser — your files and data stay on your device and are not uploaded to our servers.
Whether you are a developer, designer, student, or business owner, this tool is designed to save you time and make your workflow more efficient. Bookmark this page to access it whenever you need it — it will always be free.
Frequently asked questions
Is the QR Code Generator completely free?
Yes, the QR Code Generator is 100% free to use with no hidden charges, no subscription, and no signup required. Simply visit the page and start using it immediately.
Does this tool upload my files to a server?
No. Everything runs entirely in your browser using JavaScript. Your files, text, and data never leave your device and are never sent to our servers. This makes it completely private and secure.
Does the QR Code Generator work on mobile?
Yes, the QR Code Generator is fully responsive and works on all devices including smartphones, tablets, and desktop computers. It works on Chrome, Firefox, Safari, and Edge browsers.
How accurate is this tool?
Our QR Code Generator uses industry-standard algorithms to ensure accurate results every time. It has been tested extensively across different browsers and devices to ensure consistent and reliable output.
What is the difference between the error correction levels?
Error correction trades data capacity for damage tolerance. A higher level keeps the code scannable even if part of it is scuffed, covered by a logo, or printed slightly blurry — worth using for anything printed rather than shown on a screen.
Can I generate a QR code for WiFi or a contact card?
Yes. Switch to the WiFi tab to encode a network name, password, and encryption type so a scan joins the network automatically, or the vCard tab to encode a contact card that adds an entry when scanned.
