A free QR code generator with logo, color, and vector export
This QR Code Generator creates static QR codes that work forever — the data is encoded directly into the code, so there's no short-link that can expire and no tracking service that can disappear. Generate codes for URLs, WiFi networks, contact cards, email, SMS, phone numbers, or plain text, then style them with custom foreground and background colors or a one-click preset. Add your logo to the center for branded codes, and export as a crisp PNG or JPG for screens or a scalable SVG for print, where the code stays sharp at any size from a business card to a billboard.
Understanding error correction levels
QR codes use Reed–Solomon error correction, which lets a code still scan even when part of it is damaged, dirty, or covered. There are four levels: L recovers about 7% of data, M about 15%, Q about 25%, and H about 30%. Higher levels add more redundancy, making the pattern denser but far more resilient. If you place a logo in the center of your QR, always use Level H so the overlaid area is safely within the recoverable margin and phones can still read it on the first try.
Design tips for QR codes that always scan
Reliable QR codes come down to contrast, size, and quiet zone. Keep strong contrast between the dark modules and the light background — inverted (light-on-dark) codes scan poorly on many cameras. Preserve the quiet zone, the empty margin around the code, so scanners can find its edges. For print, export as SVG and keep the physical size at least 2×2 cm; for screens, 256px or larger is a safe minimum. Test the final code on both an iPhone and an Android device before you print thousands of copies.
Privacy: everything runs in your browser
Your QR content is never uploaded. Whether you're encoding a private WiFi password, an internal URL, or personal contact details, the entire code is generated locally with client-side JavaScript. Nothing about what you encode is sent to a server or stored, which makes this tool safe for sensitive links and credentials.
