QRCodeCraft is a free, browser-based QR code generator and educational resource. It creates every major type of QR code — WiFi, contact cards, links, WhatsApp chats, emails, phone numbers, text messages, PDFs, and app store listings — entirely on your device, with no sign-up, no watermark, and no data ever sent to or stored on our servers. Alongside the tools, our guides explain how each code type actually works, so you're not just generating a code, you're understanding what you're sharing.
A QR (Quick Response) code is a two-dimensional barcode that stores data — a link, text, contact details, or network credentials — in a grid of black and white squares. When a phone camera reads that pattern, it decodes the underlying data and hands it to the right app: a browser for a link, the WiFi settings for a network, or the contacts app for a vCard. No internet connection is needed to scan the code itself; data only flows afterward, if the decoded content is a link that opens a page.
Every QR code on this site is generated client-side, in your own browser — the text, password, or contact details you enter are encoded directly into the image and never transmitted to our servers. That said, remember that anyone who scans a code you share can access whatever it contains (a WiFi password grants network access, a WhatsApp code opens a chat) — treat sharing a code the same way you'd treat sharing that information directly.
