Make a beautiful QR code in 30 seconds — free, offline, and no sign-up. MakeQR is a free QR code generator and maker that runs entirely on your device. No account, no watermark, no server in the middle. Add your brand color and your logo, then export a sharp QR code as PNG, SVG, or PDF. WHY STATIC QR CODES A static QR code points straight to your link. It can't be redirected, paused, or held hostage later. Many "dynamic" QR apps route your code through their own server — so after you've printed it, they can start showing ads on it, or switch it off when a subscription lapses. MakeQR codes are static by design, so the QR you print today still works years from now. WHAT YOU CAN CREATE • Website / link QR code • Wi-Fi QR code — let guests join your network without typing the password • Business card (vCard) QR code — name, phone, email, company • Plain text QR code • Email, phone, and SMS QR codes MAKE IT YOURS • Custom colors to match your brand • Add your logo in the center • High-resolution export: HD PNG, vector SVG, and print-ready PDF ONE-TIME, NO SUBSCRIPTION MakeQR is free to use. A single one-time purchase removes ads forever — no monthly fee, ever. We don't think a QR code generator should charge you every month for a code you already printed. WORKS OFFLINE & PRIVATE Everything happens on your phone. Your links and contacts never leave the device, and you can create QR codes with no internet connection at all. HONEST NOTE Static QR codes can't be edited after you create them. If you need to change the destination after printing, a dynamic QR is the right tool — that's not what MakeQR does. We do one thing well: beautiful, permanent, on-device QR codes.
