A barcode generator is a free online tool that converts text, numbers, or URLs into scannable barcode images. You choose a format (Code 128, QR code, EAN-13, etc.), enter your data, and instantly download a print-ready barcode — no sign-up required.
Yes. The tool is completely free with no account, no watermarks, and no limits. Generate and download unlimited barcodes instantly as PNG or SVG files.
It supports the most widely used 1D and 2D formats: Code 128, Code 39, EAN-13, EAN-8, UPC-A, UPC-E, ITF-14, QR Code, and DataMatrix — covering retail, logistics, healthcare, and industrial use cases.
Use EAN-13 (international) or UPC-A (North America) for retail point-of-sale. Use Code 128 for shipping and internal inventory. Use QR code for URLs, menus, or any digital content linked from print.

Yes. Enter a 12-digit number and the tool automatically calculates and appends the correct check digit. For retail distribution, EAN-13 numbers should also be registered with GS1 to ensure global uniqueness.
Amazon and most major marketplaces require GS1-registered GTINs. Freely generated barcodes without a GS1 prefix may be rejected. For Amazon, Walmart, or similar platforms, purchase a registered GS1 barcode through GS1's official website.
Common causes: barcode printed too small, missing quiet zones (blank margins), low print resolution, wrong format for the data type, or insufficient contrast. Use SVG for print and always test scan before production.
No. It runs entirely in your browser — no download or installation needed. Any modern browser on desktop or mobile works.
Yes. Barcode generation happens client-side in your browser. Your data is never sent to a server, so sensitive information like serial numbers or internal product codes stays on your device.
