QR codes are often treated as a simple way to encode a URL, but they can represent many different types of data.
A useful QR generator needs to handle the data format, error correction, output quality and the final use case.
MahaVault's QR Code Generator supports several common formats:
- URL
- Text
- Phone
- SMS
- WiFi
- vCard
- Location
Error correction
QR codes include error correction so scanners can recover data even when part of the code is damaged.
The tool provides selectable error-correction levels. Higher correction can be useful for printed codes that may be scratched, folded or partially obscured.
Output format matters
The generator supports PNG, SVG and JPG.
For print materials, SVG is usually the best option because it is vector-based and can scale without becoming pixelated.
PNG is useful for digital graphics, while JPG can be convenient when a compressed raster image is preferred.
Don't forget the margin
The empty space around a QR code is important.
A QR scanner needs enough separation between the encoded pattern and the surrounding design. The generator therefore provides a margin control.
