Generate QR Codes
Free & Instant

Yes — 100% free with no hidden fees, no account required, and no watermarks. Every QR code you generate can be downloaded and used immediately, for as long as you need it.

No. The QR codes generated here are static — the destination is encoded directly into the pattern. They never expire, have no scan limits, and will keep working as long as the URL they point to is live.

All QR code generation happens entirely in your browser — nothing is sent to any server. Your URLs, WiFi passwords, and other content never leave your device. Recent QR codes are saved locally in your browser's storage only, and only you can access them.

PNG is a raster image — perfect for digital use like websites, emails, and social media. SVG is a vector format that scales to any size without losing sharpness, making it the best choice for print materials like flyers, posters, and business cards.

For screen use (websites, presentations, emails), 256–512 px works well. For standard print (business cards, flyers), use 750 or 1000 px. For large-format print like posters or banners, use the SVG format — it scales infinitely with no quality loss.

The most common causes are low contrast between the foreground and background colors (always use a dark color on a light background), a print size that's too small (aim for at least 2 cm × 2 cm), or a very long URL making the pattern too dense. Try increasing the error correction level to H for a more resilient code.

Error correction lets a QR code be read even when part of it is obscured or damaged. Level L (7%) is fine for clean digital use. Use M (15%) or Q (25%) if you plan to add a logo overlay or expect some wear. Use H (30%) for printed codes in high-traffic areas. Higher levels make the pattern more complex, so keep your URL short if using H.

Switch to the WiFi tab, enter your network name (SSID), password, and select your encryption type (WPA/WPA2 for most modern routers). Generate and print the QR code — guests scan it with their phone camera and connect instantly, no typing needed. The password is encoded inside the QR pattern itself.

Yes, without restriction. QR codes you generate here are yours to use however you like — on product packaging, marketing materials, menus, signage, or anywhere else, personal or commercial.
