QR Code & Barcode Generator

Error correction lets a QR code be scanned even if part of it is damaged or obscured. L (Low) — 7% damage tolerance, smallest QR code. M (Medium) — 15%, good all-round choice. Q (Quartile) — 25%, good for printed materials. H (High) — 30%, best if you plan to add a logo overlay or expect wear and tear. For most uses, M or Q is the right choice.

PNG is a raster image at the pixel size you selected — best for digital use, websites, and documents. SVG is a vector format that scales to any size with perfect sharpness — ideal for printing, large format displays, and professional design work. For print use, always download SVG.

Select the WiFi tab, enter your network name (SSID), password, and security type, then click Generate. When a phone scans the QR code it will automatically prompt to join your WiFi network — no typing required. This is perfect for displaying in offices, cafes, and Airbnbs. Leave the password blank if your network is open.

Code 128 is a high-density linear barcode that can encode any ASCII character. It’s widely used for shipping labels, inventory management, product packaging, and logistics. Unlike EAN-13 (which is strictly numeric and used for retail products), Code 128 supports letters, numbers, and symbols making it more flexible for internal use cases.

Yes — use the Foreground and Background color pickers to brand your QR code. One important rule: always ensure sufficient contrast between foreground and background. A dark foreground on a light background always works. Light-on-dark can work but requires testing. Very similar colors will make the QR code unscannable. When in doubt, stick to black on white.
