QR & barcode maker

How to use QR & barcode maker

1. Enter the code content

   Paste a URL, text or barcode digits, or upload a text file. Check the exact content because the generated symbol represents it rather than validating the linked destination.

2. Choose the code type

   Select QR, Code 128 or EAN-13. For EAN-13, supply twelve digits to calculate a check digit or thirteen digits with a valid existing check digit.

3. Choose output and create

   Select PNG or SVG and set the QR size when creating a QR code. Run Create result to generate the symbol with its required surrounding space.

4. Test in its intended form

   Download and scan the result using the intended reader. Test again at the printed or displayed size, preserving a clear border and enough contrast around the symbol.
