How to Generate a Barcode Online

Create a barcode from a supported value, choose a format, preview the result, and download it for your intended use.

How to use the free barcode generator

  1. Enter the text, number, or code you want the barcode to represent.
  2. Choose a barcode format that fits your scanner and application.
  3. Adjust bar width, height, colors, and whether the value appears below the barcode.
  4. Select Generate Barcode and check the preview.
  5. Download the barcode as PNG or SVG, then test it with a compatible scanner.

Which barcode format should you choose?

Different barcode formats are designed for different uses. Code 128 supports many general-purpose alphanumeric applications, while Code 39 is used in some industrial and inventory settings. EAN-13, EAN-8, and UPC-A are common retail barcode formats when paired with valid product identifiers. ITF-14 is commonly used on outer packaging and trade-item cartons. ITF, MSI, and Pharmacode have more specific requirements and use cases.

Always confirm the required format and input rules for your system. Generating a barcode image does not assign a valid retail product identifier, postal code, or other official identifier.

Barcode labels for products, clothing, and packaging

Barcode labels can help businesses identify items, track inventory, and connect physical products with digital records. The right label depends on the surface, printer, scanner, environment, and identification system. Product labels often use high-contrast printing and enough clear space around the barcode to support reliable scanning.

For barcode clothing labels, decide whether the barcode will be printed on a hang tag, a paper label, or another garment-label material. Ensure the code remains readable and is linked to the correct product or stock record. Apparel retailers may have specific requirements for SKU, size, color, or retail identifiers.

Transparent barcode labels can suit packaging where a clear label is preferred, but the background and product surface can reduce contrast. Use a suitable print design, preserve a clear area behind the bars where needed, and test the finished label on the actual package. A transparent barcode label is only useful if the barcode can be scanned reliably.

This free tool generates barcode graphics; it does not print physical barcode labels or supply label stock. Verify your printer settings, label dimensions, barcode specifications, and scanner readability before using a design in production.

What is a postal barcode?

A postal barcode is used by postal or delivery systems to encode routing or tracking-related information according to a specific postal standard. Different postal services can use different formats and encoding rules. Do not assume that a general-purpose barcode generated here is a valid postal barcode; check the requirements of the postal provider or shipping platform you use.

Barcode on a newspaper

Barcodes printed on newspapers or publications can be used for retail identification, distribution, or internal handling, depending on the publisher and supply chain. The correct format depends on the publication's identification and distribution requirements. Check the publisher, distributor, or retailer specification before generating a code for this purpose.

Need a barcode scanner app for Android?

A barcode generator creates a barcode image; a barcode scanner app for Android uses a phone camera to read a barcode. These are different functions. After downloading a barcode, you can test it with a compatible scanner app or a dedicated scanner to confirm that it returns the expected value.

Download and print a barcode safely

PNG is convenient for many documents and digital workflows. SVG is a vector format that can scale without the same pixelation associated with enlarging a raster image. Regardless of format, keep adequate contrast and quiet zones, avoid stretching the barcode, and test a printed sample at its final size before production.
