QR codes facilitate access to links, contacts, Wi‑Fi networks and other information simply by pointing the camera. With the generator above, you create codes by customizing size, margins and colors, view the result instantly and download as PNG or SVG for printing or digital use.

Best practices for readability

  • Maintain high contrast between the code and the background; avoid colors that are too light.
  • Reserve a margin (quiet zone) around the QR Code to facilitate reading.
  • Avoid distortion: do not stretch or tilt the code when inserting it into artworks.

Recommended size

For printing, it is recommended to have at least 2 cm on each side in materials close (flyers, cards) and larger for reading at a distance. For screens, 256–512 px work well in most cases.

Output formats

  • PNG: PNG: practical for general use on websites and social networks.
  • SVG: SVG: Scalable Vector Graphics, ideal for printing and artwork without quality loss.

Additional tips

  • Test the QR Code on different mobile phones and brightness levels before publishing.
  • Use short URLs to simplify the code and improve readability.
  • Avoid overlapping logos or images on the QR code's center without ensuring readability.
