FAQ

Frequently asked questions

Why do I get an "invalid format" error?

EAN-13/EAN-8/UPC-A require an exact number of digits with a valid checksum. CODE128 and CODE39 accept a more flexible format.

Is the barcode stored on a server?

No, everything is generated in your browser — data is never sent anywhere.

Which file format should I choose for printing?

SVG is best for printing and scaling without quality loss. PNG is easier to drop into documents or online stores.

Need barcodes for your whole product catalog?

e-Buhalteris has a warehouse module with bulk barcode editing and label printing.
