A barcode generator is an online tool that converts a number into a readable barcode image. When you enter your number and type, our tool formats the barcode according to industry standards and generates a downloadable image file that you can use to place on your labels or packaging.

The barcode type you choose depends on how your product will be sold or used: UPC-A: Required for most retail products in the United States. UPC-E: A compressed version of UPC-A for smaller packaging. Codabar: Used in medical, memberships, and library systems. PostNet: Designed for U.S. postal routing (primarily legacy use). Code 39: Common for asset tags, internal identifications, and non-retail applications. EAN-13: Standard for retail products sold internationally. EAN-8: A shorter EAN format designed for small packages. Code 128: Commonly used for internal inventory, asset tracking, or log

Most retail-ready barcodes should be between 1.25" and 2" wide with a minimum height of 0.5" to ensure accurate scanning. The most important factor is maintaining the quiet zone, which allows scanners to read your barcode correctly. If you're unsure about the best size, consider where the label will be applied and how the product will be handled.
