Free Barcode Generator Online - Code 128, EAN-13, UPC-A, Code 39, ITF-14

Create scannable barcode images in nine symbologies that match common retail and logistics searches: Code 128 for alphanumeric cartons, EAN-13 and EAN-8 for European style product codes, UPC-A for North American twelve digit retail, Code 39 for industrial labels, ITF-14 for case level GTIN style data, MSI for numeric inventory, Pharmacode for pharmaceutical packaging lines, and Codabar for libraries and logistics. Adjust bar width, height, human readable text, font size, foreground and background colors, then download PNG or SVG or print. Everything renders in your browser from the value you type.

Tips for the Barcode Generator

Three short notes that usually help on this page.

  • Pick the symbology your retailer or WMS expects (EAN-13 for retail, Code 128 for general logistics).
  • Test-scan with a real phone before mass printing. Leave white space around the bars.
  • Export SVG for sharp scaling. Use PNG for quick embeds in documents or email.

Nine Symbologies in One Tool

Pick the format first, then type a value that satisfies that symbology. EAN and UPC expect numeric strings with valid lengths and check digits where applicable. Code 128 accepts flexible alphanumeric payloads, which is why it dominates internal shipping labels.

  • •Code 128 for general alphanumeric encoding
  • •EAN-13 and EAN-8 for compact retail GTIN style numbers
  • •UPC-A for US and Canada style twelve digit retail codes
  • •Code 39 for legacy industrial and healthcare labeling
  • •ITF-14 for fourteen digit interleaved cases and cartons
  • •MSI for warehouse numeric tracking
  • •Pharmacode for narrow pharmaceutical strip codes
  • •Codabar for blood banks, libraries, and parcel handoffs

Retail: UPC-A vs EAN-13

Merchants selling in the United States and Canada usually photograph UPC-A symbols. Brands exporting to the EU or many Asian markets often print EAN-13. This generator draws whichever symbol you select as long as the digits you enter meet the encoder rules.

Logistics and Warehousing

Operations teams pair Code 128 with SSCC style strings or internal SKUs. ITF-14 remains common on corrugated cases when the data model expects fourteen digits. MSI still appears in older inventory stacks focused on pure numeric keys.

Sizing, Contrast, and Print

Wider bars and taller modules scan more reliably on cheap printers. Keep dark bars on light backgrounds for laser scanners and phone cameras. Toggle human readable text when pack out staff still verify digits by eye, or hide it when the label is tiny.

PNG, SVG, and Printer Friendly Export

PNG suits slide decks, email, and quick proofs. SVG scales to large label templates without jagged edges. The print action opens a clean page with the vector centered for copy rooms.

Browser Based Privacy

JsBarcode runs locally after the page loads. Your product numbers and serials never leave the tab for encoding, which matters when prototypes use confidential codes.

What This Tool Does Not Replace

Issuing official GS1 company prefixes, ISBN registrations, or centralized serial management still happens outside any free web form. Use this generator to produce artwork once you already own the numbers. For two dimensional codes such as QR, use our QR code generator.
