Frequently Asked Questions

Is my data sent to a server?
Never. All barcodes are generated entirely in your browser using JsBarcode, an open-source JavaScript library. No data is transmitted to any server.
Which barcode format should I use for my product?
For retail products sold worldwide, use EAN-13. For US/Canada retail, use UPC-A. For shipping and logistics, use Code 128. For internal inventory and warehouse use, Code 39 or MSI work well. For pharmaceutical packaging, use Pharmacode.
How do EAN-13 checksums work?
EAN-13 uses 12 data digits plus 1 check digit calculated automatically. Enter only the first 12 digits and the tool calculates the correct check digit. If you enter all 13, it validates that the last digit is correct.
Can I download in high resolution for print?
Yes. Use the PNG export scale slider — set it to 4× or 6× for high-resolution print output. Or download as SVG for infinitely scalable vector output that works at any size without quality loss.
Can I batch generate many barcodes?
Yes — switch to Batch Mode, paste one value per line, select your barcode type, and click Generate. Each barcode gets an individual PNG download button, and you can also download all as a ZIP.
