Pick a symbology, type your number or text, and set the bar width (X-dimension), height and quiet zone. BarcodeKit draws the barcode at true physical size, so a 0.33 mm EAN-13 prints at exactly the size retailers expect. Need hundreds? Paste a CSV into the bulk generator or print straight onto Avery label sheets.
Verified before you print
BarcodeKit draws every barcode from one precise geometry model, then reads it back with ZXing, an open-source scanner engine running in your browser. PNG, SVG, true-size PDF and EPS downloads all come from that same verified geometry, so what we check is exactly what you print.
Private by design
Nothing you type or upload leaves your device. There is no account, no server-side processing and no tracking of your product numbers.

Frequently asked questions
How do I know the barcode will scan?
Every barcode is read back by an open-source scanner engine (ZXing) right after it is drawn, from the same geometry we export. If the decoded value does not match what you typed you will see a warning before you download.
Which barcode type should I use?
Retail products sold in shops use UPC-A (North America) or EAN-13 (everywhere else). Amazon FNSKU and internal SKUs use Code 128. Outer cartons use ITF-14 or GS1-128. Small parts and healthcare often use Data Matrix.
Is BarcodeKit free?
Yes. Generate, verify and download barcodes as PNG, SVG, PDF or EPS with no account, no watermark and no sign-up.
Are my barcode numbers uploaded anywhere?
No. Barcodes are drawn and checked entirely in your browser. Your product numbers, SKUs and CSV files never leave your device.
Do you sell UPC or EAN numbers?
No, and we recommend you never buy them from resellers. Official UPC, EAN and GTIN numbers are licensed by GS1, the standards body. Amazon and most retailers check numbers against the GS1 database and can reject recycled ones.
