Generate Barcodes for Everyday Labels
This free barcode generator creates Code 39 barcodes directly in your browser. Code 39 is a popular linear barcode format for inventory labels, internal SKUs, warehouse bins, asset tags, sample tracking, and simple product workflows.
The generated barcode is rendered as SVG, which keeps the bars sharp at any size. You can download the vector SVG for print layouts or export a PNG when you need a quick image for documents and spreadsheets.
Inventory and SKU Labels
Turn short product codes into scannable labels for shelves, bins, packaging, and stockroom workflows without needing label software.
Print-Friendly Output
Adjust bar height, module width, and quiet zone spacing so the code has enough white space and contrast for common scanners.
SVG and PNG Downloads
Use SVG for crisp print artwork, or download PNG when you need a raster image for quick sharing, office documents, and internal sheets.
Local Browser Rendering
The barcode is generated in JavaScript on your device. Your internal IDs, SKU naming, and label content do not need to be uploaded.
