Generate QR codes from any text, URL, or data string directly in your browser. Customize the size, error correction level, and colors to match your branding. The generated codes can be downloaded as PNG or SVG for use in print materials, websites, or mobile applications.
QR codes store data in a two-dimensional grid of black and white modules. They support four error correction levels (L, M, Q, H) that add redundancy — at the highest level, up to 30% of the code can be damaged and still scan correctly. This makes them practical for printed materials that might get scratched or partially obscured.
Add scannable links to flyers, business cards, and posters that direct people to your website or landing page.

Yes. Just ensure there is enough contrast between the foreground and background for scanners to read the code reliably.
