Frequently Asked Questions

Get answers to common questions about barcodes

Is the barcode generator free?
Yes, Tool Easy Barcode Generator is completely free to use. There are no hidden charges, watermarks, or usage limits. All features are available without any payment.
What barcode formats are supported?
We support Code 128, UPC-A, EAN-13, QR Code, Code 39, and ITF-14 formats. Each format has specific use cases and data requirements that are automatically validated.
How does compression affect barcode quality?
Compression affects the file size of downloadable images. Higher compression (lower percentage) creates smaller files but may reduce image quality. We recommend 70-80% for optimal balance between quality and file size.
What's the difference between UPC and EAN?
UPC (Universal Product Code) is primarily used in North America with 12 digits, while EAN (European Article Number) is used internationally with 13 digits. EAN is essentially UPC with an additional country code digit.
Can I print these barcodes for commercial use?
Yes, barcodes generated with our tool can be used for commercial purposes. However, for retail products, you may need to register certain barcode numbers with GS1 (for UPC/EAN) depending on your location and use case.
What's the recommended barcode size for printing?
For optimal scanning, barcodes should be at least 1-1.5 inches wide and have a minimum height of 15-25% of the width. The exact size depends on the barcode type and scanning distance.
