QR Code Generator

About the QR Code Generator

A QR code (Quick Response code) is a two-dimensional barcode that can encode text, URLs, contact information, Wi-Fi credentials, and more. Any smartphone camera or QR scanner app can decode the data in under a second, making QR codes the standard way to bridge printed or physical material with digital content.

Enter any URL or text, choose an error correction level, and click Generate. The QR code is rendered directly in your browser — nothing is uploaded to a server. Download the result as a PNG for use in documents, signs, packaging, or presentations.

Error Correction Levels

QR codes have built-in redundancy that allows them to be read even when partially obscured or damaged. There are four levels, each trading off data capacity for resilience:

• L (Low, ~7%) — maximum data capacity, suitable for clean digital displays where damage is unlikely.
• M (Medium, ~15%) — a good default for most use cases including websites and marketing materials.
• Q (Quarter, ~25%) — recommended when the QR code will be printed on packaging that may get scuffed or dirty.
• H (High, ~30%) — maximum resilience, used when the code may be partially covered (e.g. overlaid with a logo).

What Can Be Encoded

QR codes can encode any Unicode text up to approximately 2 KB. Common use cases include website URLs, plain text messages, email addresses, phone numbers, Wi-Fi network credentials (WIFI:T:WPA;S:MyNetwork;P:password;;), vCard contact data, and geographic coordinates.
