Frequently Asked Questions:

What is the difference between 1D and 2D barcodes?
1D barcodes (linear barcodes) store data in parallel lines of varying widths, while 2D barcodes (like QR codes) store data in both horizontal and vertical dimensions, allowing them to hold much more information.

Is there a limit to how many barcodes I can generate?
No, you can generate unlimited barcodes completely free of charge. There are no usage limits or restrictions.

Is my barcode data kept private and secure?
Absolutely. All barcode generation happens locally in your browser. Your data is never sent to our servers, ensuring complete privacy and security for sensitive information.

Can I use the generated barcodes commercially?
Yes, all barcodes generated with our tool are free for personal and commercial use. However, for certain barcode types like UPC-A used in retail, you may need to purchase a unique company prefix from GS1.

Do I need special software to read the generated barcodes?
The barcodes generated are standard 1D linear barcodes that can be read by any standard barcode scanner or smartphone barcode reading app.
