A real barcode generator that does what the others don't
Most free online barcode generators hand you a small, watermarked PNG of a single 1D barcode and stop there. This one runs the full bwip-js symbology engine in your browser: 1D and 2D codes, GS1 application-identifier support, automatic check digits, and clean vector (SVG) output you can scale to any size without blurring. Nothing you type is uploaded anywhere.
