Frequently Asked Questions
What is a barcode and how does it work?
+
A barcode encodes data as a series of parallel lines with varying widths. A barcode scanner reads the pattern of light and dark bars and decodes them into the original text or number. Different formats follow different encoding rules for different use cases.
Which barcode format should I use?
+
Use CODE128 for general-purpose alphanumeric data. Use EAN13 for retail products sold in Europe and internationally. Use UPC for products sold in the USA or Canada. Use CODE39 for industrial labels. Use ITF14 for shipping carton labels.
Is this barcode generator completely free?
+
Yes — 100% free. No account, no sign-up, and no watermark on downloaded barcodes. You can generate and download as many barcodes as you need.
What is the difference between PNG and SVG downloads?
+
PNG is a high-resolution raster image suitable for printing labels, websites, and documents. SVG is a vector format that scales to any size without losing quality — ideal for professional printing, laser cutting, or design software like Illustrator or Figma.
Why does EAN13 show an error for my value?
+
EAN13 requires exactly 13 numeric digits. The last digit is a check digit automatically validated by the format. Make sure your input contains only numbers and is exactly 13 digits long (e.g., 5901234123457).
Can I use these barcodes commercially?
+
Yes, you can use the generated barcodes for commercial purposes. However, if you need GS1-registered barcodes (e.g., for selling in major retailers), you must obtain an official GS1 company prefix and barcode number from GS1 directly.
