Free Online QR Code Generator
QR codes bridge physical and digital. Scan with a smartphone to open URLs, join WiFi, add contacts, or trigger payments. Our free generator creates fully customizable QR codes — choose from four sizes (128–1024px), four error correction levels, custom foreground and background colors, and download as PNG or SVG.
What You Can Encode
URLs for websites and landing pages. WiFi credentials (SSID, password, encryption). Plain text for offline display. Email (mailto:) and phone (tel:) for business cards. Keep URLs under 100 characters when possible for smaller, easier-to-scan codes.
Customization Options
Choose from 128×128, 256×256, 512×512, or 1024×1024 pixel sizes. Set custom foreground and background colors to match your brand. Select error correction level L (7%), M (15%), Q (25%), or H (30%) — higher levels make codes scannable even when partially covered but increase density.
PNG vs SVG Output
PNG has fixed pixels — use for digital at a specific size. SVG is vector and scales infinitely for print (business cards, posters, signage). Both formats support custom colors and error correction settings.
QR Code Best Practices
Minimum size 2×2 cm for reliable scanning. Strong contrast between foreground and background colors. Error correction level M (15%) suits most uses; use H (30%) when adding a logo overlay. Always test with multiple devices before deploying.
Frequently Asked Questions
Do QR codes expire?
Static QR codes never expire. If the URL becomes inactive, the code still scans but leads to a dead page.
How much data can a QR code hold?
Up to 4,296 alphanumeric or 7,089 numeric characters. Shorter content produces smaller, easier-to-scan codes.
What error correction level should I use?
M (15%) works for most digital uses. Use H (30%) if you plan to overlay a logo on the QR code, as it tolerates more obscured data.
Can I use custom colors?
Yes. Pick any foreground and background color. Ensure strong contrast for reliable scanning — avoid light foreground on light background.
Are QR codes free to use?
Yes. The QR standard is open and license-free. Use for any purpose without royalties.
