Browse All ToolsA barcode generator converts text, numbers, or URLs into a scannable barcode image. Barcodes are used across retail, logistics, healthcare, and manufacturing to track products, manage inventory, and speed up point-of-sale transactions. Instead of buying desktop software or signing up for a subscription, you can use this free online barcode generator to create barcodes right in your browser.
This tool supports five of the most widely used barcode formats:
Small businesses use barcode generators to print product labels, asset tags, and warehouse bin identifiers. Event organizers create QR codes for ticket validation. Developers generate test barcodes while building scanning features into mobile apps. Marketers embed QR codes on flyers, business cards, and product packaging to link customers directly to landing pages or special offers.
Type or paste your data into the input field, select a barcode type from the dropdown, and click Generate. The barcode renders instantly in your browser with no server round-trip. Download the result as a high-resolution PNG file, or copy it to your clipboard for pasting into design tools like Figma, Canva, or Google Docs. All processing happens locally, so your data never leaves your device.

Yes, completely free with no sign-up, no watermark, and no usage limits. The barcode is generated entirely in your browser using open-source libraries, so there is no server involved and no data leaves your machine.
One-dimensional (1D) barcodes like Code 128, Code 39, EAN-13, and UPC-A encode data in a series of parallel lines with varying widths. They store small amounts of data, typically numbers or short text. QR codes are two-dimensional and store data in a grid of black and white squares, allowing them to hold much more information, including full URLs, contact cards, and paragraphs of text.
The barcode images you generate here are yours to use however you like, including on commercial products. However, if you need official UPC or EAN codes for retail distribution, you must first purchase a GS1 company prefix from GS1 (gs1.org) to get unique product numbers. This tool encodes whatever numbers you provide but does not assign or register barcode numbers.
EAN-13 requires exactly 12 or 13 digits (the 13th is a check digit that the tool can calculate automatically). UPC-A requires exactly 11 or 12 digits. If you enter letters or the wrong number of digits, the generator will show an error message explaining what is expected. Double-check your input and try again.
