What the Barcode Generator does
This tool turns a number or text string into a real, scannable barcode you can download and print. It supports six widely used symbologies: CODE128, EAN-13, EAN-8, UPC-A, CODE39 and ITF-14. That covers retail products (EAN and UPC), shipping cartons (ITF-14), inventory and asset tags (CODE128 and CODE39), and plenty of in-between cases. It is handy for small shop owners labelling stock, makers prepping products for a marketplace, warehouse teams, and developers who just need a quick test barcode.
How to use it
- Type your data into the Value field. The default sample is there so you can see the output right away.
- Open the Format dropdown and choose the symbology you need (CODE128 is the most forgiving if you are unsure).
- Watch the preview redraw as you type. The human-readable digits sit under the bars automatically.
- If you see a red message, your value does not match the format’s rules (for example UPC-A wants 11 or 12 digits). Adjust the value until the barcode appears.
- Click Download SVG to save the barcode to your device.
Why generate barcodes here
The whole thing runs on your machine, so your product codes and SKUs never leave the browser. Nothing is uploaded, there is no account to create, and there are no limits on how many you make. You also get a vector SVG rather than a low-resolution screenshot, which means the bars print crisp at any size and scan reliably on the shelf.
Tips
Validate the printed result with your phone’s camera or a handheld scanner before a big print run, and keep a quiet margin of white space around the code. Generating codes for a large catalogue? The BulkPro desktop app from the same team is built for batch label work, while this page is best for one barcode at a time.
Frequently asked questions
- Which barcode formats can I create?
- Six common formats: CODE128, EAN-13, EAN-8, UPC-A, CODE39 and ITF-14. Pick one from the Format dropdown and the preview updates instantly. If your value does not fit the chosen symbology (for example a 13-digit EAN needs exactly 12 or 13 digits), the tool shows a clear error so you can fix it before downloading.
- What file format do I get when I download?
- An SVG file. Because SVG is vector, the barcode stays razor sharp at any size, which matters for print and product labels where blurry bars can fail to scan. You can drop the SVG straight into design tools like Illustrator, Inkscape, Figma or a label template.
- Are the barcodes real and scannable?
- Yes. They are generated with a standards-based engine, so a scanner or phone barcode app reads them correctly as long as the value is valid for the format and the printed size is large enough. The human-readable digits also appear beneath the bars.
- Is anything uploaded or stored?
- No. The barcode is rendered entirely in your browser using JavaScript. Your values are never sent to a server, there is no account, and there are no usage limits.
