✅Which symbologies are supported
- CODE128 / CODE39: general 1D codes that accept letters and digits, common in logistics and warehousing
- EAN-13 / EAN-8 / UPC: retail product codes with strict digit-count requirements
- ITF / ITF-14: numeric interleaved codes, often used on outer cartons
💡Tips
- EAN-13 needs 12-13 digits and UPC needs 11-12 digits — the wrong count will error
- A larger bar width factor makes the barcode wider and sharper; lower it for small printed labels
- A failure usually means the content breaks the symbology rules — CODE128 is the most flexible
A barcode encodes numbers or characters as black-and-white bars of varying width so scanners can read them fast. They are widely used in retail, warehousing and asset tracking. This tool creates standard barcodes for you to download.
