QR Code Generator

Making a QR code

Pick a type (link, text, phone, SMS or email), enter the content and the QR code is drawn instantly. For print, download a large PNG (2000 px) or an SVG that stays sharp at any size. These are static QR codes: the content is stored in the code itself, so there's no redirect server, no expiry and no risk of it turning into an ad page later.

Tips for codes that scan reliably

• Margin — keep about 4 modules of empty space (the quiet zone) around the code.
• Contrast — dark code on a light background. Inverted codes fail on many devices.
• Size — at least 2 cm (¾ in) per side in print; for posters scanned from afar, about one-tenth of the scanning distance.
• Length — longer content means denser codes that are harder to scan. Shorten long URLs if you can.

Adding a logo

You can put your logo in the center. Because it covers part of the code, error correction is switched to Highest (30%) automatically. Don't use other companies' logos without permission, and always test-scan with a phone before printing.

Error correction

QR codes carry redundant data so they still scan when partly dirty or covered. Medium (15%) is enough for most uses; choose High or Highest for outdoor stickers or logos. Higher levels make the code denser.
