What this calculator does

QR codes encode text and URLs into a scannable two-dimensional barcode that smartphones can read with their camera. This generator creates QR codes instantly from text or URL input with configurable size and error correction level. Once generated, you can download the QR code as a PNG image. QR codes are useful for sharing website links, embedding URLs on printed materials like business cards and posters, linking physical products to digital content, and quickly transferring text between devices. Enter your content, adjust the size and error correction settings if needed, and download the image.

QR Code Generator FAQ

What error correction level should I use for QR codes?
QR codes have four error correction levels: L (7%), M (15%), Q (25%), and H (30%). Higher levels make the code more resilient to damage or partial obstruction but produce a denser pattern. M is a good default for general use.
What is the maximum data a QR code can store?
A QR code can store up to 4,296 alphanumeric characters at the lowest error correction level. In practice, shorter content produces cleaner, more easily scannable codes. Keep URLs under 100 characters for reliable scanning.
What can I encode in a QR code with this tool?
You can encode any text or URL. Type or paste your content into the input field, choose your preferred size and error correction level, and download the resulting QR code as a PNG image.
