QR code generator

How to create a QR code online

Type or paste the content you want to encode — a URL, plain text, email address, phone number, or any other text — into the input box. The QR code preview updates instantly. Scan it with your phone camera to verify it links to the right place, then click Download PNG to save a high-resolution image you can use in print materials, websites, presentations, or anywhere else.

What can I encode in a QR code

QR codes can store any text up to around 2,900 characters. In practice most people use them for website URLs, but you can also encode email addresses using the mailto: format, phone numbers using tel:, SMS messages using sms:, Wi-Fi credentials using the WIFI: format, and full vCard contact details. Use the Quick fill buttons above the options to get a ready-made template for each type.

Which error correction level should I choose

Error correction determines how much of the QR code can be damaged or obscured while still being scannable. Medium (M) is the best choice for most uses — it recovers from up to 15% damage and produces a compact code. Choose High (H) for anything printed on surfaces that might get scratched, dirty, or partially covered, such as product packaging, stickers, outdoor signs, or anywhere with a logo printed over the QR code. Low (L) produces the smallest QR code but has almost no damage tolerance — use it only in controlled digital environments.

How to download and use your QR code

Click Download PNG to save the QR code as a high-resolution PNG file. The downloaded image is generated at 10 pixels per module, which produces a large, crisp image suitable for printing at any reasonable size. For best print results, keep QR codes at least 2cm × 2cm (about 0.8 inches square). If embedding in a document or website, PNG works everywhere. For vector use in design tools, you can paste the PNG at a high enough resolution that it stays sharp at any print size.
