About Barcode Generator
Need a scannable barcode for a product label, inventory tag, or shipping system but don't want to install desktop software or sign up for a SaaS account? This generator turns a value into a clean, standards-compliant barcode in formats like EAN-13, UPC-A, and Code128, ready to drop into a print sheet or design file.
You enter the data, pick the symbology, and the tool renders the barcode instantly in your browser. Different formats have different rules, EAN and UPC enforce fixed digit counts and check digits, while Code128 handles arbitrary alphanumeric data, and the generator follows each spec so scanners read it reliably. It's free, requires no account, and adds no watermark to the output.
Common uses
- Create EAN-13 or UPC-A codes for retail product SKUs before sending artwork to a printer
- Generate Code128 barcodes for warehouse bins, asset tags, or internal tracking labels
- Produce test barcodes to validate a point-of-sale or scanner integration during development
- Add a barcode image to invoices, tickets, or packing slips in a document template

FAQ
Which barcode formats does it support?
It covers common 1D symbologies including EAN-13, UPC-A, and Code128, among others. Pick the format your scanner or downstream system expects.
Does it calculate the check digit automatically?
For formats that require one, such as EAN and UPC, the tool computes and appends the correct check digit so the barcode validates against the spec.
Can I generate QR codes here?
No. This tool produces 1D linear barcodes. QR codes are 2D matrix codes and need a separate QR generator.
Can I use Barcode Generator on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
