Barcodes are machine-readable representations of data used across retail, logistics, healthcare, publishing, and manufacturing. Choosing the right barcode format is critical using the wrong one can prevent scanners from reading your labels. UITLY's free barcode generator supports all major 1D and 2D formats with full customization and professional PNG and SVG export.
For reliable scanning, EAN-13 barcodes should be printed at a minimum of 37.29mm × 25.93mm (100% magnification). Code 128 barcodes should maintain a minimum bar height of 6.35mm. Always include a quiet zone (blank space) on both sides at least 10 times the narrow bar width for 1D codes. Download SVG format for print to ensure perfect sharpness at any size.
If you're selling products in retail stores, you typically need to register your product with GS1 to obtain a legitimate GTIN (Global Trade Item Number) for your EAN-13 or UPC-A barcode. However, for internal use, inventory tracking, document management, or custom applications, you can create and use any barcode data without registration. UITLY generates the barcode image the underlying data is yours to define.
