Free Barcode Generator — Create SVG & PNG Barcodes Online

Free Barcode Generator

Barcodes are everywhere — on retail products, shipping labels, asset tags, and even event tickets. If you need a fast, reliable way to generate printable barcodes without installing software or paying for APIs, this free Barcode Generator does the job. Our tool creates clean, standards-compliant 1D barcodes (such as Code128, EAN-13, UPC, Code39, and ITF) and allows you to download the result as SVG (best for printing) or PNG (best for immediate use).

Why this tool? Because it runs entirely in your browser: there’s no server storage, no account required, and no hidden costs. That means instant results, privacy for your data, and full control over the barcode output. Whether you’re labeling products, printing shipping stickers, or building a barcode-enabled inventory system, this tool gives you a fast path from value to printable file.

Which barcode should I choose?

Code128: the most flexible — encodes letters and numbers, great for custom product IDs.

EAN-13 / UPC-A: used in retail; make sure you have the correct number of digits and check digit if you’re creating retail barcodes.

Code39: easy for alphanumeric codes and internal use (often used in warehouses).

ITF (Interleaved 2 of 5): common for logistics and cartons.
The tool lists these options — choose the one that matches your application. (If in doubt, Code128 is a good default for internal product IDs.)

How to use Free Barcode Generator

  • Paste or type the data you want to encode. Numeric values are required for some symbologies (like EAN/UPC).
  • Select the barcode type (Code128, EAN-13, etc.).
  • Set width and height — increase height for scan reliability on printed labels.
  • Toggle “Show human-readable text” if you want the number displayed under the bars.
  • Click Generate and preview the barcode. If everything looks good, click Download and choose SVG for printing or PNG for quick use.

Printing & quality tips

Use SVG when possible — it’s vector and prints crisply at any size.

For small labels, keep a minimum module width (module = narrow bar width) around 2–3 px printed at the final size to ensure scanners can read it.

Keep a clean, quiet zone (margin) around the barcode — at least 10% of the barcode height is a good start.

Test-scan on multiple devices (phone apps, professional scanners) before mass printing.

Common use cases

Retail products: EAN or UPC barcodes for store scanners.

Inventory & asset tracking: Code128 or Code39 for flexible IDs.

Shipping & logistics: ITF for carton labels.

Labels & tags: high-contrast black on white works best.

Security & privacy

Everything happens locally in your browser with the open-source JsBarcode library, so we do not send or store your barcode data on our servers. If you need server-side generation for automation or bulk production, consider server-side barcode tools that produce PDFs or label sheets.

Accessibility & compatibility

Barcodes are scanned by laser or camera-based readers. This generator produces barcodes that are compatible with standard scanners — but remember that some retail systems require registration of GTINs (UPC/EAN) with the authorities — this tool only generates the symbol image.

FAQs

Which barcode types are supported? — Code128, EAN-13, EAN-8, UPC-A, Code39, ITF, MSI, Pharmacode.

Can I download vector files? — Yes, download SVG for print or PNG for raster use.

Are these barcodes valid for retail use? — The images are generated correctly, but retail EAN/UPC requires valid GTIN numbers and registration with authorities; this tool doesn’t register codes.

Do you store my data? — No. Everything is generated client-side.
