How this barcode generator works
This page creates barcode and QR images in your browser with JavaScript. Nothing is uploaded, and no generated images are stored on our servers. That keeps the tool fast.
For retail use, choose the format your system requires (for example EAN-13, UPC-A, or ITF-14). Then verify your identifier and check digit before you print labels in volume.
For standards and identifier licensing, follow official GS1 guidance for your region.
Retail & inventory labeling
Generate SKU and product ID labels for shelf tags, bin locations, receiving workflows, and POS systems. Keep the same format across your ERP, marketplace feed, and printed labels to reduce mismatches.
Marketing & QR destinations
Create QR codes for product pages, campaign links, menus, and app deep links. Use short URLs and test scan speed on low-light mobile cameras before printing at scale.
Barcode vs QR code: when to use each
- 1D barcodes are best for product IDs, SKU workflows, POS scanning, and packaging labels.
- QR codes are better for URLs, app links, contact cards, and marketing destinations.
- Print with high contrast and leave enough quiet zone around the symbol, so scanners read it reliably.
- Always test on the actual scanner hardware and mobile camera apps you expect users to use.
Print and scan quality checklist
- Use dark symbols on a light background with high contrast.
- Preserve quiet zones (empty margins) around the code edges.
- Do not scale the image much after download. Export at the target size when you can.
- For packaging, validate scans on both handheld scanners and mobile devices.
- Recheck check digits and format rules before high-volume print runs.
