Generate local barcode symbols and label sheets
- Enter or import exact identifiers and quantities.
- Review encoded values and any calculated check digit.
- Set physical page/label dimensions and generate locally.
- Inspect counts, approve omissions and download.
Formats, output and limits
Code 128, Code 39, EAN-13, UPC-A and static QR. SVG, PNG, ZIP and actual label PDFs. Up to 2,000 rows, 5,000 labels, 250 sheets and 100 MiB generated output.
Spreadsheet-safe CSV: risky text gets the visible prefix text: . Preview: =1+1 becomes text: =1+1; full-width formula starters and leading control characters are handled too. Validated numeric amounts keep their signs. Use JSON, where available, for original text and XLSX for typed exchange.
A worked example
EAN-13 data 400638133393 becomes 4006381333931 after its check digit is calculated. A wrong supplied check digit is rejected.
Common questions
Does this register retail numbers?
No. Supply identifiers allocated to you. Generating a symbol does not issue GS1 numbers.
Will leading zeros survive?
Text identifiers remain exact. Ambiguous numeric spreadsheet cells are warned or rejected; lost digits cannot be reconstructed.
Can I put a logo inside a QR code?
Choose Static QR and select a local logo image. The same small logo appears in each QR code in the batch. Scan a sample at the size you plan to use.
How should labels print?
Use actual size / 100 percent and the alignment test PDF. Physical print/scanner verification is still your responsibility.
