Frequently Asked Questions (FAQ)
How do I create and download a barcode for free?
Choose your required symbology (e.g. UPC-A, Code 128, or QR Code), type your numbers or text, adjust optional bar dimensions, and click 'Download SVG' for infinite resolution vector artwork or 'Download PNG' for high-resolution 300 DPI raster printing.
What is the difference between UPC-A and EAN-13 barcodes?
UPC-A is a 12-digit numeric barcode used predominantly in the United States and Canada for retail point-of-sale scanning. EAN-13 is a 13-digit standard utilized in Europe, the UK, Asia, and globally.
Can I use these barcodes to sell products on Amazon FBA and retail stores?
Yes. Barcodes generated on Barcode Generator Pro conform strictly to GS1 General Specifications and ISO/IEC standards. Once you possess a valid GS1 Company Prefix and assigned GTIN, you can generate and download commercial-grade vector SVG barcodes here.
Why should I use Vector SVG instead of PNG for commercial printing?
Vector SVG format uses mathematical coordinate paths rather than pixel rasters. This guarantees that your barcode prints with razor-sharp bar edges at any press resolution without pixel blurriness that causes point-of-sale scanner rejections.
