Create Code 39 barcodes free in your browser. A legacy alphanumeric format still used in industrial, automotive and ID applications. SVG and PNG export.
Code 39 encodes uppercase letters, digits and a few symbols. It is older and less dense than Code 128 but is still required by some industrial and government systems.
Use Code 39 when a specific legacy system requires it. For new internal projects, Code 128 is usually the better, more compact choice.
1. Open the generator and enter your value. 2. The code is validated and previewed instantly, with a scannability check where it applies. 3. Download a crisp SVG for print or a PNG for screens — or switch to bulk mode to make many at once from a list or spreadsheet. Everything happens on your device.
No registration is needed for Code 39. If you have a choice, consider Code 128 for denser, more modern encoding.
This generator is free, requires no account, adds no watermark, and runs entirely in your browser. The data you enter is never uploaded. Codes are static — they don’t expire and don’t depend on our servers.
