Everything You Need to Know About QR Codes
QR codes (Quick Response codes) have become an essential bridge between the physical and digital worlds. Originally developed in 1994 for the automotive industry to track parts, these two-dimensional barcodes have evolved to facilitate everything from contactless payments to quick Wi-Fi sharing and digital business cards.

How Does Error Correction Work?
One of the most powerful features of a QR code is its built-in error correction, which utilizes the Reed-Solomon algorithm. This means that a QR code can still be successfully scanned even if it is partially damaged, covered, or dirty. When generating your code, you can select the correction level: L (Low, 7%), M (Medium, 15%), Q (Quartile, 25%), or H (High, 30%). Higher correction levels result in a denser pattern, which is particularly useful if you plan to print your codes in an environment where they might incur wear and tear.
SVG vs PNG Format
Our tool supports both PNG and SVG exports. PNG is a raster image format suitable for immediate use on screens or standard printing. SVG (Scalable Vector Graphics), however, is a vector format that maintains infinite resolution without pixelation, making it strictly superior for professional printing, large banners, or importing into design software like Adobe Illustrator or Figma.
Encoding Web URLs and Data Payloads
If you are encoding web URLs or complex payload data into your QR code, ensure your link parameters are properly encoded using our URL Converter. For embedding structured JSON data, format and validate your payload structure first using our JSON Formatter.
