How to create a barcode

Checklist

1. Choose the format required by the receiving system (UPC-A, EAN-13, Code 128, Code 39 or ISBN-13).
2. Enter the value exactly, preserving leading zeroes and meaningful letter case.
3. Resolve any format or check-digit error before using the preview.
4. Download PNG, SVG or PDF and test the printed result with the actual scanner and software.

Print checklist

• Keep a clear quiet zone on either side of a linear barcode.
• Use clean, high-contrast print; do not stretch, clip or place text across the bars.
• Do not cut down retail EAN/UPC bar height just to fit a design.
• Print at 100% scale; confirm module width and bar height before a full batch.
• PNG resolution matters at final size; SVG scales without raster pixelation; PDF is a document, not proof of a scan.
