Bulk Barcode Generator

The tool uses the JsBarcode library to encode your input according to the selected barcode standard. Each standard defines how characters map to patterns of bars and spaces -- for example, Code 128 uses variable-width bars encoding 3 characters per pattern with a built-in checksum. The encoded pattern is rendered as an SVG or drawn onto an HTML Canvas. Batch mode iterates through all inputs and packages the rendered barcodes into a ZIP archive.

Four standard 1D formats: Code 128 (general-purpose alphanumeric), EAN-13 (international retail), UPC-A (North American retail), and Code 39 (logistics and inventory). Code 128 is the most flexible and accepts any ASCII text.

Yes. Switch to Batch mode to create up to 500 barcodes at once. Enter values one per line, generate a sequential range with an optional prefix (e.g. SKU-001 to SKU-500), or upload a CSV file. All barcodes download as individual PNGs in a single ZIP archive.

Export your product codes as a CSV file and upload it in Batch > CSV mode. The tool reads the first column of each row as a barcode value. You can also copy-paste a column directly into the List input (one value per line).

EAN-13 requires 12 or 13 digits, UPC-A requires 11 or 12 digits, Code 39 accepts uppercase letters, digits, and a few special characters, and Code 128 accepts any text or number.

Yes. The generated barcodes follow the official encoding standards and can be scanned by any standard barcode reader. Download as PNG and use in your label design software. Batch mode lets you generate all your product labels at once.
