Online Barcode Generators

A barcode serves as a graphic image designed to encode data, much like how different languages such as French and English use the Roman character set for letters. These barcodes have seamlessly integrated into various aspects of modern life and find application in a wide array of uses. While there are numerous online barcode generators and tools available to create barcode images, it is vital to comprehend the distinctions between these tools and the types of barcode images they produce.

Ensuring consistent and accurate scanning of generated barcodes poses a common challenge. Barcodes that fail to scan properly can lead to supply chain disruptions, a subpar customer experience, and potential compliance penalties from certain trading partners. The first step in determining the most suitable barcode generator is to identify the intended usage or display of the barcode image. Will it be utilized on a website, incorporated into product packaging, integrated into a label, or printed on a poster?

It is essential to consider various graphic file formats as well. While common low-resolution formats like JPG and PNG are suitable for web graphics, they should NEVER be used when a barcode is meant to be included within package designs or printed labels. Barcode images destined for traditional printing press should ALWAYS be vector-based (.eps) and include a parameter called “bar width reduction” to compensate for the bar growth that occurs during the printing process. Using incorrect file formats and neglecting to include the compensation factor can result in unscannable printed barcodes that appear too dark.
