What barcode formats are supported?
This tool supports Code 128, EAN-13, UPC-A, Code 39, ITF-14, and Pharmacode barcode formats, covering most retail, logistics, and industrial applications.
What is Code 128?
Code 128 is a high-density linear barcode that can encode all 128 ASCII characters (letters, digits, and symbols). It is widely used in shipping, packaging, and inventory management due to its compact size and versatility.
What is EAN-13?
EAN-13 (European Article Number) is a 13-digit barcode standard used globally for retail products. The first 2-3 digits represent the country code, followed by the manufacturer code, product code, and a check digit.
What is UPC-A?
UPC-A (Universal Product Code) is a 12-digit barcode primarily used in the United States and Canada for retail products. It consists of a manufacturer code, product code, and a check digit.
What is Code 39?
Code 39 is one of the oldest barcode symbologies. It can encode uppercase letters (A-Z), digits (0-9), and a few special characters. It is commonly used in automotive, defense, and healthcare industries.
What is ITF-14?
ITF-14 (Interleaved 2 of 5) is a 14-digit barcode used for shipping containers and cartons. It encodes the GTIN-14 number and is designed to be printed on corrugated cardboard.
What is Pharmacode?
Pharmacode (also known as Pharmaceutical Binary Code) is a barcode standard used in the pharmaceutical industry for packaging control. It encodes a single number between 3 and 131070.
Can I download the generated barcode?
Yes, you can download the barcode as a PNG image file or copy it as SVG code for use in design software. Both formats are suitable for printing.
How to choose the right barcode format?
For retail products, use EAN-13 (global) or UPC-A (North America). For logistics and internal tracking, Code 128 is ideal. For shipping cartons, use ITF-14. For pharmaceutical packaging, use Pharmacode.
Is this barcode generator free?
Yes, this tool is completely free with no registration required. You can generate unlimited barcodes directly in your browser.
Are the generated barcodes scannable?
Yes, all generated barcodes follow international standards and can be scanned by any standard barcode scanner or smartphone camera app.
What is the difference between 1D and 2D barcodes?
1D barcodes (like Code 128, EAN-13) store data horizontally using parallel lines. 2D barcodes (like QR codes) store data both horizontally and vertically, allowing much more information to be encoded.
How to Use Barcode Generator
Turn any text or number into a scannable barcode in seconds. Generation happens entirely in your browser — nothing is sent to a server.
- Type the content to encode into the input field — for example Hello World or a product number.
- Choose the symbology from the format options: Code 128, EAN-13, UPC-A, Code 39, ITF-14 or Pharmacode.
- Adjust the size settings such as the 1–4 scale and 30px or 50px modules until the preview looks clean.
- Check the live preview to make sure the barcode renders correctly.
- Download the barcode as PNG for printing or as SVG for scalable editing.
EAN-13 and UPC-A accept digits only — if your content contains letters, switch to Code 128 or Code 39.
