Frequently Asked Questions:

What is a barcode?
A barcode is a machine-readable representation of information displayed as a series of parallel lines and spaces. Barcode scanners read these patterns and convert them into digital information.

What is the difference between 1D and 2D barcodes?
1D barcodes store information horizontally using lines and spaces. Examples include UPC-A and Code 128. 2D barcodes such as QR Codes store information in both horizontal and vertical directions, allowing them to contain significantly more data.

Can I generate unlimited barcodes?
Yes. There are no restrictions on the number of barcodes you can create using this tool. You can generate as many as needed for personal or commercial projects.

Is my data secure?
Absolutely. Barcode generation occurs directly in your browser. Your information is not uploaded, stored, or shared with external servers.

Can I use the generated barcodes commercially?
Yes. The barcode images generated by this tool can be used for business purposes. However, some barcode formats such as UPC-A may require officially assigned product numbers from organizations like GS1.

Do I need special equipment to scan these barcodes?
No. Most barcode scanners, POS systems, and many smartphone applications can read standard barcode formats generated by this tool.
