Is this barcode generator free?

Yes. You can create previews and download PNG files without payment or sign-up.

Do you store or upload what I type?

No. Encoding runs in your browser after the page loads. Your content is not sent to our servers for generation.

Which format should I use on retail packaging?

It depends on your supply chain. Common retail product barcodes are often EAN-13 or UPC family codes; this tool includes a dedicated EAN-13 generator plus Code 128, GS1-128, Code 39, and other logistics-friendly symbologies. Confirm requirements with your retailer or GS1 programme.

What is the difference between QR Code and Data Matrix?

Both are 2D symbols. QR Codes are very common for URLs and marketing. Data Matrix is often chosen for small labels and industrial marking. Pick the one your process or partner specifies.

About this generator

Use this page to turn text, URLs, GS1 element strings, or structured carrier payloads into a scannable image. The preview updates as you type, and you can save a PNG for printing or screen use.

More than one hundred symbologies are available—retail, logistics, postal, healthcare (HIBC), GS1 composites, and specialty codes. Always test important labels with the same scanner or app you will use in production; sizing, quiet zones, and contrast affect real-world reads.
