QR codes that just scan.

A QR (Quick Response) code is a two-dimensional barcode that stores data as a pattern of black and white squares. When scanned with a phone camera, it instantly opens the encoded content — typically a URL, but it can also contain text, email addresses, phone numbers, WiFi credentials, or vCard contact details.

Yes, completely free with no sign-up required. The QR code is generated entirely in your browser — no data is sent to any server. You can customise colours, size, and error correction level, then download as PNG or SVG.

Error correction adds redundant data to the QR code so it can still be scanned even if part of it is damaged, dirty, or obscured. Level L recovers 7% of data, M recovers 15%, Q recovers 25%, and H recovers 30%. Higher levels make the QR code denser but more resilient.

Yes. You can change both the foreground (module) colour and the background colour using the colour pickers or the quick preset buttons. Maintain high contrast between the two for best scanning reliability.

Use SVG for print materials (business cards, flyers, signage) as it scales to any size without losing quality. Use PNG for digital use (websites, emails, social media). The PNG download uses the pixel size you configure in the tool.

For reliable scanning, a QR code should be at least 2cm × 2cm (about 0.8 inches) when printed. For outdoor signage or scanning from a distance, scale up proportionally — a good rule of thumb is the QR code width should be at least 1/10th of the expected scanning distance.
