Use high contrast (dark bars on light background) for better scanning
Leave quiet zones (white space) around the barcode - at least 10x the bar width

Test scan with multiple devices before mass printing
For QR codes, ensure minimum size 2cm x 2cm for reliable scanning
Avoid distorted or stretched barcodes - maintain aspect ratio
🔧 Troubleshooting Common Issues
❓ Barcode not generating?
Make sure you have entered valid data for the selected barcode format. Some formats have specific requirements (e.g., EAN-13 requires 12-13 digits). Check the hint text below the input field.
❓ Barcode not scanning?
Increase the barcode height, ensure good print quality, and check for sufficient contrast between bars and background. Also make sure there's enough white space around the barcode.
❓ Downloaded PNG is blurry?
Our barcodes are generated as vector SVG and converted to high-resolution PNG. Make sure you're downloading the PNG, not taking a screenshot. Use the download button, not right-click save.
❓ QR Code not working on mobile?
Ensure the QR code is large enough (minimum 2cm x 2cm) and has good contrast. Some QR code readers require better lighting conditions.
