The barcode generator is a powerful online tool that supports multiple mainstream barcode formats, including CODE128, EAN, UPC, CODE39, ITF, MSI, Pharmacode, Codabar, and CODE93. You can freely adjust every parameter of the barcode: from bar width and height, foreground line color and background color, to whether to display text, text content, font, font size, alignment and position, to overall margins or individually setting top, bottom, left, and right margins. All generation is done locally in the browser with no data uploaded to any server, ensuring both speed and security. If you have multiple items to encode, simply enter one per line to batch generate and download as a ZIP file, perfect for inventory management, logistics labels, and more.
What barcode formats are supported?
We support almost all mainstream 1D barcode formats, including CODE128 (auto/A/B/C modes), EAN-13, EAN-8, EAN-5, EAN-2, UPC(A), UPC(E), CODE39, ITF, ITF-14, MSI series, Pharmacode, Codabar, and CODE93. Different formats suit different scenarios: EAN-13 is commonly used for retail products, CODE128 for logistics and warehousing, and Pharmacode for pharmaceutical packaging.
Which parameters can be customized?
You can customize a rich set of parameters: barcode format, bar width, barcode height, line color, background color, whether to display text, custom text content, font, font style (normal/bold/italic/bold italic), text alignment (center/left/right), text position (bottom/top), font size, text margin, and overall margin or individually setting top/bottom/left/right margins. These options let you create barcodes that perfectly match your brand style.
Is batch generation supported?
Yes. Simply enter different content on each line in the text box and click the batch generate button. The system will generate a corresponding barcode for each line. All generated barcodes will be neatly displayed below, and you can download them individually or use the batch download feature to package them all into a ZIP file at once.
Will my data be sent to a server?
No. The entire barcode generation process is completed locally in your browser. We do not collect, store, or upload any of your data. This guarantees both speed and the security of your privacy.
