Generate high-quality linear barcodes online. Support Code 128, Code 39, EAN-13, and UPC formats instantly.
Need to generate barcodes for your products, book inventories, or event tickets? Our online Barcode Generator allows you to convert text or numbers into standard barcode patterns instantly. Download your generated barcodes in high-quality SVG or PNG formats for printing.
The generator supports Code 128 (most popular for general use), EAN-13, EAN-8, UPC-A, and ITF formats, ensuring compatibility with retail scanners worldwide.
| Barcode Type | Characters Supported | Best Use Case | Data Capacity |
|---|---|---|---|
| Code 128 | Alphanumeric (ASCII) | Shipping labels & asset tracking | High capacity |
| EAN-13 | Numeric Only (12 + 1 checksum) | Retail products (International) | Fixed length |
| UPC-A | Numeric Only (11 + 1 checksum) | Retail products (North America) | Fixed length |
| Code 39 | Alphanumeric, spaces, symbols | Industrial & military applications | Moderate capacity |
Code 128 is highly recommended as it is compact, supports letters, numbers, and symbols, and is readable by almost all standard barcode scanners.
Yes, as long as you select standard formats (like EAN-13 or Code 128) and print them clearly on paper without blurring the bars.
UPC-A is the standard retail barcode in North America (12 digits), while EAN-13 is the international standard retail barcode (13 digits) used worldwide.
Yes. By default, generators render the human-readable text labels beneath the barcode lines. You can toggle this setting in the configuration.
Always print barcodes in black ink on a solid white background. Using red, light colors, or patterned backgrounds will cause scanning failures.
Currently, the online tool is designed to generate single barcodes to allow precise styling and configurations.
SVG is the best format for printing as it is a vector format that scales infinitely without losing sharpness. PNG is best for digital use.
No. EAN-13 and UPC-A only support numbers. If you need to encode letters, use Code 128 or Code 39.
Yes. Barcodes are generated locally using JavaScript libraries, meaning your data never leaves your browser.
A 2D barcode (like a QR code) encodes data horizontally and vertically, holding much more information than a standard 1D linear barcode.
