How to: Barcode Generator
- Choose the barcode type and enter the value.
- Adjust size, colours and text.
- Download PNG or SVG.
Barcodes are used for inventory, shipping, libraries, retail and events. Pick the symbology your scanner or partner needs and download a print-ready image.
Common uses
- Label inventory and assets.
- Create shipping and carton labels (ITF-14).
- Make library or membership cards.
Tips for best results
- Code 128 is the most versatile for general use.
- Print SVG for crisp bars.
- Leave white space (quiet zone) around the barcode.
Choosing a symbology
Code 128 is compact and encodes all ASCII characters – the best general choice. EAN-13 and UPC-A are for retail products. ITF-14 is used on shipping cartons. Code 39 suits badges and assets. Codabar is used in some libraries and blood banks.
Printing tips
Print at high contrast, keep quiet zones clear and test with the scanner you will actually use. SVG output stays sharp at any size.
