Barcode Generator

Barcode Generator creates scannable barcodes — Code 128, EAN-13, UPC-A, and more — as downloadable PNG images. Type in your numbers, get a print-ready barcode.

When to use it

Labeling products for retail (UPC-A/EAN-13), tagging inventory or assets (Code 128), creating library or membership cards, or generating barcodes for shipping and warehouse systems. If something needs to scan at a register or with a scanner gun, this makes the barcode.

How to use it

1. Open Barcode Generator and choose the barcode format (Code 128 for general use, EAN-13/UPC-A for retail products).
2. Enter the numbers or text to encode.
3. Download the barcode as a PNG. Each generated barcode = one document of quota.

What the output looks like

A crisp PNG image of the barcode with the human-readable numbers beneath the bars — suitable for printing on labels, packaging, or documents.

Good to know

• Pick the right format. Retail products need EAN-13 (international) or UPC-A (North America) with properly registered numbers. Internal inventory can use Code 128, which encodes more data.
• Retail barcodes aren't just numbers — EAN/UPC numbers must be legitimately assigned to your product (via GS1) or registers may reject them.
• Print at 100% scale or larger. Shrinking a barcode too far makes it unscannable — test-scan every design before a big print run.
• High contrast matters: black bars on white. Fancy colors and busy backgrounds behind barcodes cause scan failures.
• Quiet zones (the blank margins on either side of the bars) are part of the barcode — don't crop them off.
