About QR Code Generator
QR codes (Quick Response codes) are two-dimensional barcodes that smartphones can scan instantly. This free online QR code generator converts any text, URL, Wi-Fi credentials, contact card, or plain message into a high-resolution PNG QR code — entirely in your browser, with no watermark, no registration, and no expiry. Unlike services that route scans through their own servers, a QR code generated here encodes your data directly, so it works forever and never leaks what it contains.
Common uses include linking printed materials to websites, sharing Wi-Fi passwords without typing, adding vCard contact details to business cards, generating payment links, marking assets and equipment, and embedding app download links. Choose the output size (128px for web thumbnails up to 1024px for print) — larger sizes scan more reliably from a distance or when printed small.
The generator runs locally using a JavaScript QR encoder. Your content never leaves the browser, making it safe for internal URLs, tokens, or confidential text. For best scanning reliability, keep the payload short (URLs under ~150 characters), preserve the default quiet zone, and test a scan before mass printing.
Frequently Asked Questions
Do the generated QR codes expire?
No. The data is encoded directly into the image — there is no redirect service that could shut down. The code works as long as the target content exists.
Can I use the QR codes commercially?
Yes. QR code generation is not patent-restricted and the output is yours to use in print, packaging, posters, or products with no attribution required.
What size should I print?
A rule of thumb: the printed QR code should be at least 1/10th of the scanning distance. A code scanned from 1 meter away should be at least 10 cm wide.
