Your settings and recent values are stored only in this browser, so they carry over next time you open this page. EAN/UPC formats calculate the final check digit automatically. For print, we recommend a bar width of 2+, height of 60+, and margin of 10+. Everything runs entirely in your browser.

How to use

Pick a barcode format (Code 128, EAN-13, etc.). Leave the value empty and click "Random" to fill in one that fits the format.

Enter a value that matches the format, and the barcode updates live in the preview.

Adjust colors, size, and whether text is shown, then use "Download" to save it as PNG or SVG, or "Copy image" to paste it directly.

FAQ

자주 묻는 질문

Q1. Is the value I enter sent to a server?

No. The barcode is generated entirely in your browser and the value you enter is never sent to or stored on a server. Your recent values and settings like color and size are saved only in this browser, though, so they carry over next time you open the page.

Q2. Which barcode formats are supported?

Code 128, Code 39, Code 93, EAN-13, EAN-8, UPC-A, UPC-E, ITF-14, ITF, MSI, Codabar, and Pharmacode. Each format has its own allowed length and characters — see the note shown under the value field.

Q3. Can I use a generated barcode on a real product?

The format and checksum are generated correctly, but real retail barcodes (EAN, UPC, etc.) require a unique number registered with an official issuing agency. Use this tool for testing or internal labels rather than production retail packaging.

Q4. Why won't a scanner read the barcode I generated?

If the value's length or character type doesn't match the chosen format's spec, the checksum comes out wrong and scanners will reject it. EAN-13 needs 12 digits and UPC-A needs 11, for example — check the on-screen note for your format's exact requirements. Low contrast between the background and bar colors can also cause scan failures; the Colors section shows a contrast warning when that happens.

Q5. Can I download it as PNG instead of SVG?

Yes. Click "Download" under the preview to choose between a 3x-resolution PNG for print or a lossless SVG, or use "Copy image" to paste it straight into another program.
