How to use Barcode generator

Create local Code128-B, checked UPC-A or DataMatrix ECC200 codes as self-contained SVG or PNG.

  1. Choose local input and settings, or try the labelled synthetic sample. File selection does not read content; processing starts after the explicit action.
  2. Code128-B:1–80 ASCII chars · UPC-A:11 data/12 checked digits · DataMatrix:1–150 ASCII chars/≤64 modules per side · scale2–8.
  3. Static black/white symbols, 10-module linear and four-module DataMatrix quiet zones. No GS1/FNC1/ECI, product-number assignment or tracking. UPC check digit is calculated or validated. DataMatrix may be square or rectangular. Review exported codes with intended retail/print scanners; compatibility is not guaranteed.
  4. Review the preview and exported result. Cancel stops the disposable local worker; edit/Clear/leave discards old results and download links. Input files are not changed or uploaded; working data is not saved to an account. Downloaded files remain on your device.
