Yes. The barcode is generated directly in your browser — nothing you type is uploaded to our servers.
CODE128 works for arbitrary text and numbers and is the most flexible choice. Use EAN-13, EAN-8, or UPC for retail product barcodes, ITF-14 for shipping cartons, and CODE39 or Codabar for logistics and legacy systems.
Formats like EAN-13, EAN-8, and UPC require a specific, fixed number of digits and only accept numeric input. If your value doesn't match that length, switch to CODE128, which accepts arbitrary text and numbers of any length.
SVG is a vector format that stays sharp at any size, which is best for printing on labels or packaging. PNG is a fixed-resolution image, which is fine for screens or quick digital use.
Yes, as long as the value is valid for the chosen format and the barcode is printed at a reasonable size with good contrast. Avoid shrinking it so much that the bars become too thin to scan reliably.
