Frequently Asked Questions

What is Code-128 barcode format?

Code-128 is a high-density linear barcode symbology that can encode all 128 ASCII characters. It's widely used in shipping, packaging, and inventory management due to its compact size and excellent readability.

What characters can I use in Code-128 barcodes?

Code-128 supports the full ASCII character set including uppercase and lowercase letters, numbers, punctuation marks, and special characters. This makes it versatile for various applications.

What's the difference between SVG, JPG, and PNG downloads?

SVG is vector-based and can be scaled without quality loss. JPG is best for photographs but may compress barcode details. PNG is lossless and ideal for digital use with transparent backgrounds.

Why is my barcode not scanning properly?

Common issues include insufficient quiet zones (margins), low contrast, incorrect bar width for the scanning distance, or printing resolution issues. Ensure your barcode meets industry standards for size and quality.

Can I use these barcodes for commercial purposes?

Yes, all barcodes generated with our free tool can be used for personal and commercial purposes without any restrictions or attribution required.

What are the optimal dimensions for printing barcodes?

For most applications, 1-2 inch width with proportional height works well. Ensure your printer supports at least 300 DPI resolution and test print a sample before mass production.

Do you store the barcodes I generate?

No, all barcode generation happens locally in your browser. We don't store your data, barcode content, or generated images on our servers, ensuring complete privacy.
