Barcode Generator
The Barcode Generator creates real, scannable barcodes — CODE128, CODE39, EAN-13, UPC-A, and ITF-14 — right in your browser. Type your content, pick a format, and download a clean PNG. Nothing is uploaded.
Any letters, numbers, or symbols.
Barcodes are generated in your browser and are real, scannable codes. CODE128 is the best all-purpose choice; use EAN/UPC for retail products and ITF-14 for shipping cartons.
How This Tool Works
Enter the text or numbers you want to encode, choose a barcode type (CODE128 works for almost anything), and a scannable barcode is drawn instantly. Click Download PNG to save it.
Formula & Method
Each barcode symbology encodes characters as a specific pattern of bars and spaces of set widths, with a check digit where the format requires one. This tool uses the JsBarcode engine to render valid, standards-compliant codes locally in your browser.
Example Calculation
Type a product code like 012345678905, choose UPC-A, and the tool renders the retail barcode with its check digit, ready to download and print on a label.
Frequently Asked Questions
Are these barcodes actually scannable?+
Yes. They are generated with a standards-compliant engine, so a phone or retail scanner reads them like any printed barcode. For best results, print at a good size and keep the white space around it.
Which format should I use?+
CODE128 is the best all-purpose choice — it handles letters, numbers, and symbols. Use EAN-13 or UPC-A for retail products, and ITF-14 for shipping cartons.
Why won't my content generate?+
Some formats are strict: EAN-13 needs 12–13 digits, UPC-A needs 11–12 digits, and ITF-14 needs exactly 14 digits. If your input doesn't fit, switch to CODE128, which accepts almost anything.
Is my data private?+
Yes — the barcode is created entirely in your browser and nothing you type is uploaded to or stored on any server.
