Frequently Asked Questions

What's the difference between barcode formats?

Different barcode formats are optimized for specific use cases. CODE128 is versatile for general use, EAN/UPC formats are standard for retail products, while specialized formats like Pharmacode are designed for specific industries. Each format has different character support and data capacity.

Should I use PNG or SVG format?

Use PNG for digital displays, websites, and basic printing. Choose SVG for professional printing, large-scale applications, or when you need scalable vector graphics that maintain quality at any size. SVG files are also smaller and more suitable for web integration.

How do I ensure my barcodes scan properly?

Ensure high contrast between bars and background, maintain adequate quiet zones (white space) around the barcode, use appropriate size for your scanning distance, and test with multiple devices. Avoid stretching or distorting the barcode proportions.

Can I use these barcodes commercially?

Yes, the generated barcodes can be used for commercial purposes. However, for retail products requiring official EAN/UPC codes, you may need to obtain registered numbers from GS1 or your local numbering organization to ensure uniqueness in the global marketplace.

What data can I encode in barcodes?

This depends on the format selected. CODE128 supports most ASCII characters, while EAN formats only accept numbers. CODE39 supports alphanumeric characters, and specialized formats like Pharmacode have specific requirements. The tool provides real-time validation for each format.
