Barcode Generator Manual

Use Single mode for one symbol or Bulk mode for up to 500 values. Choose the barcode type before entering data because each format has its own character and length rules.

Single generation

1. Choose a barcode type and size.
2. Enter the value.
3. Select Generate barcode.
4. Review the encoded value and check-digit status.
5. Download SVG or PNG, or use Print / Save PDF.

Bulk generation

Paste one value per line, or import a local CSV, TSV, or TXT file up to 2 MiB. For tabular files choose the value column and optionally a filename column. Invalid rows are reported and are not packaged as barcode files. The ZIP includes a manifest.

Identifier boundary

The app can validate structure and render symbols. It does not issue, license, register, certify, or verify ownership of GTIN, UPC, EAN, or ISBN identifiers.

Printing

Keep the generated white background and surrounding quiet area. Print at 100% / actual size when practical and test a sample with the intended scanner before a production run.
