Is anything I type, scan or open uploaded?

No. Barcodes are drawn in your browser, and camera frames, pictures and CSV files are processed on your device. Nothing is stored and nothing is sent to our server, and it's all gone when you close or reload the page.

Does making a UPC or EAN barcode register my product?

No. A barcode is a picture of a number. Retail product numbers (GTINs such as UPC and EAN) are licensed from GS1, which links them to your company; making a barcode image here doesn't assign or register a number. Retailers and marketplaces may check numbers against GS1's records.

Is JustYourBarcode free?

Yes. Every tool is free with no sign-up and no limits on use, including commercial use of the barcodes you make. Clearly labeled ads keep it that way.

Does it work on my phone?

Yes. The tools work in any modern browser on phones, tablets and computers, and the scanner uses your phone's camera.

Free barcode tools that keep your data private

JustYourBarcode is a free set of barcode tools that run in your browser. Make retail barcodes (UPC-A, EAN-13, EAN-8, ISBN), logistics barcodes (Code 128, GS1-128, ITF-14), older symbologies such as Code 39, Code 93, Interleaved 2 of 5, Codabar and MSI, and 2D codes such as Data Matrix, PDF417 and Aztec. Type your data, see the barcode straight away and download it, with no account and no watermark.

Everything happens on your device. The numbers you type, the pictures you open, the CSV files you turn into barcodes and the frames from your camera when you scan are processed in the browser and are never sent to our server. That makes the tools safe for unreleased products, stock lists and anything else you'd rather not share.

Beyond plain barcodes there are design barcodes with art rising from the bars, a camera scanner and a picture reader, bulk generation and label sheets, and calculators for check digits, UPC to EAN and ISBN conversion. A barcode only encodes a number: for products sold in shops, the number itself comes from GS1.

Popular uses

Barcodes for products you sell, using your GS1-licensed UPC or EAN
Back-cover barcodes for self-published books
Code 128 labels for stock, bins, assets and documents
Carton and pallet barcodes for shipping (ITF-14, GS1-128)
Checking a number's check digit before you print thousands of labels

Tips for the best result

Print barcodes with dark bars on a white or light background; red, yellow and orange bars don't scan with red-light scanners.
Keep the blank margins (quiet zones) either side of the bars clear of text and edges.
Test a printed sample with a real scanner or the scanner on this site before a large print run.
